REPAIRS GONE WRONG

I upgraded to a Samsung Galaxy Z Flip 3. This phone is extremely slippery with the type of material used on the outside. I accidentally dropped the phone and the one side button remained in the "in" position and would not get out of safe mode. I took it to my branch and they tried to release the button, but no joy. It went in for repairs on the 16th January, 2022. I was told to phone the repair centre every day to get things going for the repair. I tried and went around in circles, first to customer service and then wait for 20 minutes and back to the customer service, so I gave up on that. I sent a complaint to Cell C and was given a case number of *** with a promise of a response in 24/48 hours. This was on the 31st January, 2022. I got an sms to phone the repair centre a few days ago and remembering the previous experience I had, did not expect any joy. I first spoke to a customer service agent who told me the repairs were over R10000-00 but that I should hold on the line for the repair centre to tell me what my excess would be since I am insured. The phone went dead so I called back and spoke to someone else who gave me a direct number for repairs. I duly phoned that number and got a long engaged tone and a message "the number you have dialed does not exist". I called back for the 3rd time and was told that the number given was incorrect but that I would be transferred to the repair centre. Again, just an engaged signal. I phoned back and was given another number (the original number given to me previously as above). Eventually I got through and was told a claim form would be emailed and I should send it back. 4 hours later an email appeared with ticket nr: 588661 with a claim form. I filled this out and sent all supporting documents and have sent the email 7 times because it comes back as undelivered because the mail box is full!!!!!!!!!. I then tried to fax the paperwork through, but it stays engaged and has redialed 20 times with no joy. How on earth can this process continue in this way with no assistance. For a side button that should have been replaced and that very high quote, really now??? I just want the repair centre to acknowledge my claim form and documents and get things going. If this is at all possible......
