After the mechanic fixed the car door handle, they three masks in the passenger side and trash.
The passenger seat became dirty after the repair. He made my seat dirty by touching it. Also, he might spill some kind of fluid. I called the car center, they did not answer. Bad service continued. Who will compensate my damage?
Answer my comment.

The manager did not receive my phone call and did not respond to it.
I was waiting the whole day. He called me back at 5:00pm. This is the first bad customer service experience.
The European blonde female receptionist did not make my appointment correctly on the computer system. When I got there on time,
 She and another mechanic told me that I cannot receive the repair service because there is no appointment. They did not even mention that we are sorry. The mechanic said that my door handle is not even ready. This is ridiculous. The worst customer service. The store manager apologized me and reset the appointment at 3:00pm. I will go there continuing to waste my time and car fuel. and see what happens.
