CELL C ******** call center not helpful

Cell c just decides to cancel my line for no reason. I was not able to receive calls nor Giving me a reason all of a sudden that they need to load R1 to my account, because all of a sudden this needs to done for them to unblock my account. My subscription is paid in full. And then I had to hear how my subscription is and what is paid to the account is in a negative and the R1 will resolve this??? ***????????????I have 6071 free minutes???? why why why is my line cancel completely ????????????????????????????????????????? When I told Sandile Gumede I'm not going to put the phone down until they unblocked my account he said well he will have to drop the call as he is not allowed to hold on. He kept on telling me he did active my line but I still couldn't phone anyone. I asked to speak to a manager and Sandile "puts me through" just to drop the call. Thank you for the worst service and not activating my account. as this issue was never my fault nor my problem I did not owe Cell C any money!!!!!!! There was no reason for this. Call Ref ***
