Warning when dealing with Cell C

So sick and tired of Cell C complete incompetence when dealing with the Customers. Cell phone has been disconnected even although payment has been received. There was a small error in April payment one digit was left out. Correspondence was sent even in previous review done on Cell C. They even acknowledged on this page that payment has been received and they notify accounts. Still on Thursday last week disconnected the service. Even a lawyer from accounts confirmed with my husband the account is up to date. Someone else phoned and said we still owing for April payment and there a small interest amount, which we not paying as the account is up to date. We personally went through to East Rand Mall branch took all the proof of payments and confirmation from Hello Peter.com got them to scan the documents to Head office reference number *** and ***. WE HAVE PAID FOR A SERVICE WE ARE UNABLE TO USE. WE WILL NOT DO A DEBIT ORDER AS CELL C PREVIOUSLY DEDUCTED A DOUBLE AMOUNT AND THAT AFFECTED OUR FINANCES. CELL C NOW HAS 2 DAYS TO FIX THE RECONNECTION OF THE SERVICE AS MY HUSBAND WILL PHONE CLIENTELE. WARNING EVERYONE OUT THERE DONT DEAL OR TAKE A CONTRACT WITH Cell C. There accounts and customer care Staff completely ******** and totally Useless
