Questions & Answers about Служба поддержки приняла претензию.

Why is приняла feminine?

Because the subject, служба, is a feminine singular noun.

In the past tense, Russian verbs agree with the subject in gender and number:

• он принял = he accepted
• она приняла = she accepted
• оно приняло = it accepted
• они приняли = they accepted

Even though служба поддержки means support service or customer support, the head noun is служба, which is feminine, so the verb is приняла.

Why is it служба поддержки, not служба поддержка?

Because поддержки is in the genitive case. Russian often uses this pattern to express something like X of Y.

So:

• служба = service
• поддержка = support
• служба поддержки = service of support, which naturally means support service

This is a very common Russian structure:

• центр города = city center
• чашка чая = cup of tea
• отдел продаж = sales department

So поддержки is not the subject here. It is dependent on служба.
