Where is my Cell Phone?

I have been a cell c-customer for 8 years on contract. the call centre in PMB has always been an unpleasant place to visit because of the long waiting (/12 hour - 2 hour wait) for service. I sent my phone in for repairs again - it has not worked since I got it. I have received NO notifications in 3 MONTHS (!!) to tell me where my phone is. The staff in Liberty Mall - the Manager in particular was EXTREMELY rudeas I have misplaced my job card. I had an ID am am on the computer system, which was verified. He accused me of 'negligence' and 'abusing' a fellow customer - this customer had become angry because she wanted service and I was taking too much time. I abused no customer. the salesman did not step to calm her or reassure either of us. There was no apology for the bad service. They said my phone 'might' be in the back. WHERE IS MY PHONE? I have been given a broken one, had my sim swopped with another customer and been treated disgustingly. I am not going to renew either of my two contracts with Cell C. The manager indicated he did not need my business. CAN I AT LEAST HAVE MY PHONE BACK?
