Shocking Service from CELL C

On December 2017 I went to Edgars Active at Bridge City to purchase a contract phone for my niece who had just finished Her Martic. We were approached by a guy wearing a blue Cell C shirt who the helped me open my account with all the documents that one requires to open an account. This went well We got the phone signed the contract and went home. Fast forward to February 2018 and my niece calls me and tell me that has phone has been blocked due to unpaid fees, This left me baffled because I have money in my account and I have had since December. So on 10 March I went to Bridge City Cell C shop to see what was the problem. I was helped by a lady called Zama, I told her my story and she said to me maybe FNB was offline and if FNB is offline when they(Cell C) try to debit the money then that could be the cause. I was once again baffled at what she said so I went to FNB and asked them about this at which they laughed at me and said no such thing. So I took my 3 months bank statemenst and went back to Zama at Cell C and showed her my 3 months statements at which we browsed and she saw that Cell C had not tried to debit from my account. So she went to her PC and checked what was the problem and we found out that the guy who opened my account had used the wrong details. He used my standard bank account and not my FNB account which he was supposed to use hence that's why I gave him my FNB 3months banking statements. So I asked Zama what must I do and why is this my fault when its Cell C who caused this F up. She said I must go and find the guy and ask him, so I said but he laso works for cell C and she said he does not work for Cell C and was rude. Now this has messed up my credit rating and left a BITTER taste in my mouth about Cell C and the people they deploy in black areas (malls). SHe did not even try to call the Call Centre and talk to people there she was just rude and brushed me off. This is unacceptable servicfrom Cell C and their staff. We work hard to get our Credit scores up to date and to have a careless mistake that can potentially damage my credit rating and still have a rude person assit me was disgusting.
