Cell C service pathetic

<p>I opened a contract with cell c not even 6 months and Im already regretting it. I had a problem with my phone when it was delivered, i sent the phone back with everything but when they returned the new phone there was no sim and I had to buy my own sim card. I have been trying to do a sim swap forever with no luck whatsoever, now they have billed me R56 more than the contract amount, when I called this morning between 8.37 - 9.10 I was being verified (they asked my name, surname and the bank I bank with) I gave that information and was told that I failed the verification. How in the world do I ****** fail giving the same ****** information that I gave when I opened the contract, they debited more than they should have on the same ****** bank account that belongs to the same bank I provided the consultant with. This is beyond ridiculous. I never changed my details, so did Cell C allow a ********* to amend my details????????</p> <p>Can this company train their consultants and upgrade their security.</p>
