bad service

<p> I had two contract with cell c and both were settled in august 2016. last year september cell c tried debit R9490.96 from my account and when i enquired about it, i was told it was a computer glitch and not to worry. in 15 march 2017 when i tried to apply for credit, i discovered that i was owing cell c the same amount they tried to debit in 2016. called them and i was told that both accounts were closed but one of the accounts wa not cleared with the credit bureau. my complaint was to be forwarded to the IT department and within 7 days i will have confirmation that my name was cleared. 7 days have passed and i have no heard anything from cell c, i try to call them and i am being transfered from one department to another. this is very frastrating because it is affecting my credit score and i have been a loyal customer but to be treated like this is very unacceptable .</p>
