Messing up my account

<p>I have been trying to update my account since saturday and now they tell me that I cant upgrade because last year there were 2 rejected debit orders. However last year I phoned the accounts department and gave them more than enough notice to cancel the debit orders and they didnt. I phoned to complain about this but nothing happened. They lady I spoke to said the reference number will be smsed to me. Nothing received. Noe I cant upgrade because you messed up. How is that acceptable? Vodacom you are losing to your competitors!</p>
