SLOW AND LACK OF SERVICE THEREOF

I have 2 contracts with cell c. I was due for an upgrade on both contracts in December 2014. I was planning not to upgrade because of the bad reception cell c has. I phoned cell c 4-5 times the one day to cancel my contracts, by the end of the day, nothing had been cancelled. This is due to the excuses received during all 4-5 phone calls ranging from agent needing to reboot their computer, to the system being slow, to reception being lost so some of the calls got dropped. A few weeks later I decided to upgrade one of the contracts due to my failure to end these contracts. When I got to a store, they had no stock (Pavillion) and they made me aware that I was owing R172. This is because Cell C was still debiting the wrong account for 1 of the contracts after I had phoned to update my bank details! I deposited and used the contract with no outstanding balance as reference. I then phoned cell c to inform then and the said the deposited amount would be allocated to the right contract. I went to the store a week later only to find that the deposited amount still hadn't been allocated correctly and was told to come back to day. I have just phoned and guess what? Still no allocation!!!
