Beyond poor treatment

My Current Cell C account was ment to end in October/ November, I did receive a call from a guy from cell c asking to upgrade an i requested him to cancel the contract. A month later i called in and spoke to another lady and she informed me that my contract was not cancelled so i requested again and she said she will do so. Since the Celle C has been allocating my normal data, minutes and sms which i found very strange. I was also put on short time at work and eventually retrenched, which i did notify Cellc and my other people who debit me every month. Fortunately i am back at work on short time. I now tried to call Cell C to organise to pay my account infull, only to find thay Cell C has handed me over which is not right, due to i was never called, never email or notified in any way whatsoever that i am falling behind and never notified that i am and has been handed over to the Lawyers in any way or form and my sim that i requested to be put on pay-as-you-go has been completely blocked from receiving any calls and sms which is a negative when clients, family or anyone tries to call me. I can not even login to the app to check. The lady i spoke to did not seem to want to help me in any way whatso ever as well or even provide me with a statement or an amount i must pay, she did not even want to give me details of the lawyers that i have been handed over to so i can contact to arrange payment, this is poor and beyond bad treatment to someone who has been a very loyal client who has never missed payment till now
