Bad Service, Rude Agents

I have a 2017 Sony XZ, which has been into the repair shop 3 times, and has to go for a 4th.

I phoned Vodacom repairs on ********** to find out what could be done, since the phone is doing exactly the same thing as before it got repaired.

Spoke to a very rude call agent, which said they cannot take my word for it, I have to take it to repairs again.

For Those interested: 1. Phone died. no lights, no charging, nothing. "replaced" phone 2. Screen started pulling away from frame, dropping calls on 5 months old "replaced" phone. 3. Phoned not having any GSM signal, randomly, every few seconds. 4. Phone still doing #3.
