CellC's ***** department

I got SMS's from CellC stating that someone is trying to do a sim swop on my number and that if it wasn't me, I should phone cellc and report it, I did this an no one was able to assist me. Thereafter I received an SMS saying that my contract has almost been approved. I did not request a contract, so I decided that I should report it and this time I won't take no for an answer. They put a block on my account - told me that the ***** department will phone me within 48 hours. It is 3 weeks later and no one has phoned me. I cannot buy data, I cannot update my limits. NOTHING. I've been a loyal customer for 4 years now and all CellC has done, is make my life difficult
