वापसी टिकट रद्द कीजिए और रिफंड लीजिए।

Yes—here वापसी टिकट means return ticket, and वापसी is functioning like a modifier of टिकट.

A few useful points:

• वापसी comes from the idea of returning / coming back.
• In this phrase, it works much like a noun used attributively: the ticket for the return journey.
• Hindi also very commonly uses रिटर्न टिकट in everyday speech.

So:

• वापसी टिकट = return ticket
• एक तरफ़ा टिकट = one-way ticket

This is a normal and natural phrase in Hindi.

Because रद्द is not the full verb here. The full verbal expression is:

• रद्द करना = to cancel

So in the sentence:

• रद्द कीजिए = please cancel

This is a very common Hindi pattern:

• noun/adjective-like element + करना = to do X / make X happen

Examples:

• शुरू करना = to start
• बंद करना = to close / stop
• साफ़ करना = to clean
• रद्द करना = to cancel

So रद्द carries the core idea cancelled / cancellation, and कीजिए is the polite imperative form of करना.

कीजिए is a polite command/request form of करना (to do).

So:

• कीजिए = do, please
• रद्द कीजिए = cancel it, please

This form is used with आप-level politeness. It is respectful and appropriate in customer-service situations, formal requests, or instructions.

Compare:

• रद्द करो = cancel it (informal)
• रद्द कीजिए = please cancel it (polite)
• रद्द करें = please cancel it / cancel it (also polite, slightly different tone)

Yes, लेना literally means to take, but in Hindi it is also often used where English would say get, receive, or collect.

So:

• रिफंड लीजिए literally: take the refund
• natural English sense: get/receive the refund

This is very normal Hindi usage. Similar examples:

• दवा लीजिए = take the medicine
• सीट लीजिए = take a seat
• रसीद लीजिए = take the receipt
• रिफंड लीजिए = take/get the refund

So even though take may sound slightly different in English, the Hindi phrasing is perfectly natural.

Because modern Hindi very often uses borrowed English vocabulary, especially for travel, business, technology, and administration.

So words like these are extremely common:

• टिकट = ticket
• रिफंड = refund
• बैंक = bank
• फोन = phone
• फॉर्म = form

This kind of mixing is completely normal in everyday Hindi. In many contexts, the English-derived word is actually more common than a pure Sanskrit/Hindi alternative.

So this sentence is not “bad Hindi”—it sounds natural and modern.

Because Hindi generally prefers Subject–Object–Verb order, and the verb usually comes near the end.

So the structure here is roughly:

• वापसी टिकट = object
• रद्द कीजिए = verb phrase

Then:

• और = and
• रिफंड = object
• लीजिए = verb

So the sentence follows a very normal Hindi pattern:

• object + verb
• object + verb

English often puts the verb earlier, but Hindi usually saves it for later.

Because not every object in Hindi needs को.

In this sentence:

• वापसी टिकट रद्द कीजिए
• रिफंड लीजिए

both टिकट and रिफंड are being used as direct objects without को, which is very natural.

Hindi uses को in many cases, especially with:

• specific people
• animate/direct objects
• affected or marked objects in certain contexts

But inanimate objects often appear without को, especially in straightforward commands like this.

So:

• टिकट रद्द कीजिए = natural
• रिफंड लीजिए = natural

It is polite and suitable for formal or service-related situations.

The forms कीजिए and लीजिए show respectful speech, typically associated with आप.

Tone-wise, it sounds like:

• a polite instruction
• a customer-service direction
• a formal request

Less formal versions might be:

• वापसी टिकट रद्द करो और रिफंड लो।
  This is informal and would be used with someone close, younger, or in a non-formal setting.

Another polite version is:

• वापसी टिकट रद्द करें और रिफंड लें।

That also sounds polite, a bit more like written instruction or formal announcement style.

These are all polite forms, but they differ a little in style.

1. कीजिए / लीजिए

Very common polite imperative.

• रद्द कीजिए
• रिफंड लीजिए

2. करिए / लीजिए

Also polite, often heard in speech.

• रद्द करिए
• रिफंड लीजिए

For करना, both कीजिए and करिए are used. कीजिए is very common and sounds standard.

3. करें / लें

Also polite, often slightly more formal, written, or instructional.

• रद्द करें
• रिफंड लें

So in practice:

• कीजिए / लीजिए = polite spoken instruction
• करें / लें = polite, often slightly more formal or written

No gender is being shown in the imperative forms here.

That is important for learners because English speakers often expect some agreement issue, but here:

• कीजिए
• लीजिए

do not change based on whether the person addressed is male or female.

Also, there is no past-tense agreement here, so you do not have to worry about the kinds of gender changes you see in sentences like:

• मैं गया / गई
• वह बैठा / बैठी

This sentence is a polite command, so gender is not marked in the verb forms.

Yes, but in real life the version with टिकट and रिफंड is often more natural.

Possible alternatives might be:

• वापसी का टिकट रद्द कीजिए और धनवापसी लीजिए।
• वापसी टिकट रद्द कीजिए और पैसे वापस लीजिए।

A few notes:

• धनवापसी is a more Hindi/Sanskrit-style equivalent of refund, but it sounds more formal and less everyday.
• पैसे वापस लीजिए is very understandable and natural.
• टिकट is so common that replacing it often sounds unnecessary.

So for everyday modern Hindi, the original sentence is very normal.

A simple pronunciation guide is:

vaapsī ṭikaṭ radd kījie aur rifaṇḍ lījie

A rough English-friendly approximation:

vaap-see ticket rudd kee-jee-eh or refund lee-jee-eh

A few pronunciation notes:

• वापसी → vaap-see
• टिकट → ti-kut / ti-kət
• रद्द → roughly rudd
• कीजिए → kee-jee-eh
• और → or / aur
• लीजिए → lee-jee-eh

The borrowed English words may be pronounced a bit differently from standard English when spoken in Hindi.

Yes, you could, but it is not necessary because कीजिए and लीजिए already sound polite.

You could say:

• कृपया वापसी टिकट रद्द कीजिए और रिफंड लीजिए।

That is grammatical, but it may sound a bit more formal or written.

In many everyday situations, just using the polite imperative is enough:

• वापसी टिकट rद्द कीजिए और रिफंड लीजिए।

So:

• कीजिए / लीजिए already carry politeness
• कृपया adds extra explicit politeness or formality
