Learn Turkish: Otelde aldığımız hizmetten hiç memnun değilim. - I am not pleased at all with the service that we received at the hotel.

This uses the new pattern you're learning: the object participle -dık (meaning 'that/which') attached to the verb base al (receive/take). Then we add the possessive ending -ımız (our) to show who received it. So, aldığımız acts like an adjective meaning 'our-received', modifying the word hizmet (service).

Why does the -dık ending change to a ğ in aldığımız?

This happens because of consonant mutation. When you add a vowel ending like -ımız to the suffix -dık, the hard k at the end softens into a ğ to make it easier to pronounce.

The English translation says 'pleased with', so why does hizmetten use the 'from' ending (-ten)?

In English, we say we are pleased with something, but in Turkish, the adjective memnun (pleased/satisfied) always demands the ablative case (-dan/-den/-tan/-ten). You have to think of it as being pleased from the service (hizmetten).
