Poor service!!!!!! MTN KATHU

I upgraded in March 2024 to the new Honor 90. The phone keep switching itself off (restart). I went to MTN Kathu for assistance to no avail, they just say someone will phone me. 5 days later 25/03/24. I booked the phone in as something is wrong. They just took the phone and completed the documents. the next day they requested the charger, I then took it in. One week later I went there to get an update, the supervisor then said I must bring the watch (gift received with the phone) as that might be the problem, I never used the watch but took it to the shop. no communication or update was given since. Today I went there again (waited 30 min for service) only to here that they can only follow up on Friday. the service is pathetic with limited to no communication. I battle now as I have to borrow a phone to stay connected and MTN KATHU just say "the contract say that we are not liable". I have to pay the upgraded fees but no phone to justify my payment. MTN, please look at your service in Kathu it is non existing!
