Cell c

I have 4 contracts with cell and I have never missed a payment. For the past 2 weeks I have been requesting to do a simswap for 1 of my numbers and when I finally got through to someone that can assist me i was put through all the security questions and I was tol that the simswap was done n I should wait 2 to 4 hours. I called them back because my simcard wasn't active yet only to find out the Sim swap wasn't done n I had to go through all the questions again. I was told to wait for the Sim to be active and as always the Sim wasn't working, I then again called cellc and I was told that they make notes on my number for someone to call me ba k, waited 2 days again n nobody called back. I tried them again this morning and I was told I did not pass the security questions and I have to wait 24 hrs. My account was more than I usually pay this month n when I called to find out it was due to get more service of which I canceled in December and I was told by your rude call center agent that I was gonna have to wait for them to resolve their matter with cellc cause on their side they have cancelled the service but money was taken out of my account without my knowledge and I am gonna have to wait 30 days to get it back. I am so utterly disgusted by cell c because if I don't pay my account, I would be called e ery minute but I have to struggle with my account.
