Useless customer "service" from Cell C

In May this year I paid my account in full in order to upgrade earlier and change my package, over the weekend a ridiculous debit went off my account.When I enquired what it was for, I was told it is the difference of the current credit on my account and what I should have paid to have my conteact paid up.I told them it was paid in full in May!!!!I was asked to send the proof of payment, which I did and when I phoned back on Monday.A case was never opened and ai had to send proof again!So I once more sent proof of payment...Then I receive an sms to once again send proof of payment to another e-mail address, *** e-mail bounced back as the e-mail does not exist!!!!My money is still not back in my account and now you can't get hold of the call centre...My reference number is ***...Its been 4 days now and no call or resolve!!Be sure I will NOT renew my contract and I want the debit order cancelled!!!I want my money bac****I am beyond livid and tired of having to make phone call after phone call!!!
