Lost Payments & Barred Service

I have a Cell C contract which I pay on time each month but each and every month I get a phone call from Cell C's call centre telling me that my account is in arrears and that I have not made payment, most times my service even gets barred and usually takes days to reactivate which is very frustrating . Apparently the payments I make go into the incorrect account, the account of my previous contract (prior to upgrade). This better be sorted out this month or I will never do business with Cell C again. Really unacceptable!!!<br> <br>
