We contacted the second point at the Skala shopping center. The essence of the problem was the SIM card board, the connection could not be found and the back cover was replaced, the iPhone 12 mini phone.
They gave me the phone on March 8, the master said it would be ready on March 10-11, the deadline, and they gave me a replacement iPhone 6s phone. They took the phone only on the 20th. After replacing the rear window, the protective rings on the camera disappeared, the master said that he took them off when he changed the glass, he took off the protective rings and put them on in a minute, but when it was time to pick up the phone, he said that he needed to remove the glass again and put a new one and asked to pay for it again.
Initially, he did not install them, the glue has dried up and everything needs to be redone.
I do not recommend contacting this network to repair your phones.
There is no feedback on phone repair, you need to call yourself and find out information, repair deadlines are not met.
