بدلا من أن تلغي الطلب، اتصل بخدمة العملاء.

بدلًا من means instead of or rather than.

So in this sentence:

• بدلًا من أن تلغي الطلب = instead of canceling the order

A small spelling note:

• In everyday writing, you will often see بدلا من
• In fully vocalized MSA, it is بدلًا من

They are the same expression.

Because Arabic commonly uses the pattern:

• بدلًا من أن + imperfect verb

when the thing being compared is an action.

So:

• بدلًا من أن تلغي الطلب = instead of canceling the order

If what follows is a noun or verbal noun, أن is not needed:

• بدلًا من الإلغاء = instead of cancellation
• بدلًا من القهوة = instead of coffee

Because in Arabic, أن + imperfect verb often corresponds to an English infinitive or gerund.

So أن تلغي is literally something like:

• that you cancel

but in natural English, after instead of, we usually say:

• instead of canceling

So the Arabic structure and the English structure are different, even though the meaning matches well.

ألغى is the past tense form: he canceled.

Here Arabic needs the imperfect form after أن, so it becomes:

• تُلغي

This is the verb ألغى / يُلغي = to cancel.

A useful mini-pattern:

• ألغى = he canceled
• يُلغي = he cancels / he is canceling
• تُلغي = you cancel / you are canceling

So أن تلغي means to cancel or canceling in this context.

Because the verb is from Form IV, and its imperfect stem is different from the past.

You learn it as:

• ألغى → يُلغي

So the hamza that appears in the past form does not stay as a separate hamza in the imperfect the way an English speaker might expect.

Then the person prefix changes:

• يُلغي = he cancels
• تُلغي = you cancel / she cancels

So تلغي is exactly the expected imperfect form.

It is the subjunctive because it comes after أن.

In full vocalization, it would be:

• أن تُلغيَ

In normal Arabic writing, those final short vowels are usually not written, so you just see:

• أن تلغي

For many learners, the important practical point is:

• أن usually makes the following imperfect verb subjunctive

Because Arabic verbs already show the subject.

So تلغي already contains the idea of you here, and اتصل also means contact! addressed to you.

Arabic often leaves subject pronouns out unless they are needed for emphasis or clarity.

So Arabic says:

• أن تلغي
• اتصل

not usually:

• أن أنت تلغي
• أنت اتصل

As written, اتصل is the masculine singular imperative, so it is addressed to one male or used as a general default in some contexts.

If you were speaking to one woman, you would say:

• بدلًا من أن تلغي الطلب، اتصلي بخدمة العملاء.

Notice:

• اتصل → masculine singular
• اتصلي → feminine singular

The earlier verb تلغي often looks the same in ordinary unvowelled writing, so the imperative اتصل / اتصلي is what makes the gender clear here.

الطلب means the order.

Arabic uses الـ here because it is talking about a specific order already known from context, just like English says the order.

Grammatically, الطلب is the direct object of تلغي, so in full case marking it would be:

• الطلبَ

But in normal modern writing, the final case ending is usually not written, so you just see:

• الطلب

Because the verb اتصل normally takes the preposition بـ when it means contact / get in touch with.

So:

• اتصل بخدمة العملاء = contact customer service

This is a very common pattern:

• اتصل بمديرك = contact your manager
• اتصل بالشرطة = contact the police

So the بـ is not optional here in standard usage.

It is an iḍāfa construction, often called a genitive construction.

Literally, it is:

• خدمة = service
• العملاء = the customers

So word-for-word it is:

• service of the customers

But in natural English, that becomes:

• customer service

Important iḍāfa points:

• the first noun usually does not take الـ
• the second noun makes the whole phrase definite if it is definite

So:

• خدمة العملاء = the customer service / customer service

After the preposition بـ, the phrase is in the genitive:

• بخدمةِ العملاءِ in full vocalization

Because Arabic normally expresses customer service as خدمة العملاء, literally service of customers.

Using the plural is natural here, just like English customer service refers to service for customers in general.

So العملاء is not talking about one customer; it refers to customers as a class.

It is pronounced roughly:

• ittaṣil

This is the imperative of:

• اتصل – يتصل = to contact / communicate / get in touch

A useful set:

• اتصل = contact! (to one male)
• اتصلي = contact! (to one female)
• اتصلوا = contact! (to a group)

Yes. A common alternative is to use a verbal noun instead of أن + verb:

• بدلًا من إلغاء الطلب، اتصل بخدمة العملاء.

This also means:

• Instead of canceling the order, contact customer service.

So both are good:

• بدلًا من أن تلغي الطلب...
• بدلًا من إلغاء الطلب...

The version with أن تلغي feels more directly tied to you canceling, while إلغاء الطلب is a little more noun-like: the cancellation of the order.
