В отзыве я написала, что техподдержка помогла быстро, но ждать пришлось долго.

В отзыве means in the review.

It uses the preposition в + the prepositional case because it means location in an abstract sense: in a review, in a letter, in an article, etc.

• отзыв = review, feedback
• в отзыве = in the review

This is very natural Russian:

• в письме = in the letter
• в статье = in the article
• в сообщении = in the message

Because написала is the feminine past tense form.

In Russian past tense, verbs agree with the gender of the speaker or subject:

• я написал = I wrote, if the speaker is male
• я написала = I wrote, if the speaker is female

So this sentence tells us the speaker is female.

Написала is perfective, while писала is imperfective.

Here, написала is used because the speaker refers to a completed action: she wrote the review / wrote in the review and finished doing so.

• писала would focus more on the process or background
• написала focuses on the result: the text was written

In this sentence, that completed-result meaning fits best.

Что here means that and introduces a subordinate clause.

So:

• я написала, что... = I wrote that...

This is very common in Russian:

• Я думаю, что... = I think that...
• Он сказал, что... = He said that...
• Мы знаем, что... = We know that...

Техподдержка is short for техническая поддержка and means technical support.

It is very common and natural, especially in everyday speech, online reviews, customer service contexts, and IT-related language.

Compare:

• техподдержка = tech support, support team
• техническая поддержка = technical support, the full form

Both are correct. Техподдержка is simply shorter and very frequently used.

Because техподдержка is the subject of the clause, so it stays in the nominative case.

• техподдержка помогла = technical support helped

The verb помочь can mean to help someone, but here the sentence does not explicitly mention whom they helped. The idea is just that technical support was helpful / provided help.

If you wanted to say whom they helped, you would normally use the dative:

• техподдержка помогла мне = technical support helped me

Yes, both are possible.

• техподдержка помогла быстро
• техподдержка быстро помогла

Both mean roughly the same thing: technical support helped quickly.

The difference is mostly one of emphasis and rhythm:

• быстро помогла often emphasizes the speed a little more directly
• помогла быстро sounds very natural too, especially in a review-style sentence

Russian word order is more flexible than English, so adverb placement often depends on style, emphasis, or flow rather than strict grammar rules.

Пришлось comes from прийтись and here means had to or it turned out necessary.

So:

• ждать пришлось долго = it was necessary to wait a long time / we had to wait a long time

This is a very common Russian structure. It often sounds a bit more impersonal than a direct I had to or we had to.

Examples:

• Мне пришлось уйти. = I had to leave.
• Нам пришлось ждать. = We had to wait.
• Пришлось отменить встречу. = We/I had to cancel the meeting.

Because пришлось is used with an infinitive to express that something had to be done.

So the pattern is:

• пришлось + infinitive

Examples:

• пришлось ждать = had to wait
• пришлось звонить = had to call
• пришлось объяснять = had to explain

Here:

• ждать = to wait
• пришлось = had to

Together: had to wait.

Russian often leaves the subject unstated when it is clear from context or not important.

In this sentence, the person who wrote the review is clearly talking about their own experience, so ждать пришлось долго naturally implies something like:

• мне пришлось долго ждать = I had to wait a long time

But Russian often prefers the shorter, more impersonal version in this kind of comment or review.

This makes the sentence sound natural and less self-centered, which is common in reviews and complaints.

Because долго is an adverb, and it describes the verb ждать.

• ждать долго = to wait a long time / to wait for long

By contrast:

• долгий
• долгое
• долгая

are adjective forms, and adjectives describe nouns, not verbs.

Compare:

• долгое ожидание = a long wait
• ждать долго = to wait a long time

Because Russian punctuation normally separates subordinate clauses and coordinating clauses with commas.

1. Comma before что

   • я написала, что...
   • The comma marks the start of the clause introduced by что.

2. Comma before но

   • ..., но ждать пришлось долго
   • но means but, and it connects two contrasting parts, so a comma is required.

This punctuation is standard Russian grammar.

Yes. Но introduces a contrast.

The sentence presents two ideas that do not fit together very smoothly:

• техподдержка помогла быстро = technical support helped quickly
• ждать пришлось долго = but it took a long time to wait / but we had to wait a long time

The nuance is something like:

• the support itself was effective or fast once it happened,
• but the overall waiting time was still long.

This kind of contrast is very typical in reviews: one part is positive, another part is negative.

Yes, the main past-tense verbs are perfective:

• написала from написать
• помогла from помочь
• пришлось from прийтись

That matters because the sentence talks about completed facts:

• the review was written,
• the support did help,
• the waiting ended up being necessary.

This gives the whole sentence a factual, summary-like tone, which is exactly what you would expect in a review.
