Account Problems

A week ago, I received a notification that my account was in arrears. Checking the account, indeed the debit order did not go off. I attempted to make a manual payment via internet banking but due to my customer number being ported from Nashua Mobile and not conforming to the usual Vodacom customer naming convention, Internet Banking complained about the reference number being invalid and would not let me proceed with a manual payment. Therefore, I logged on to the Vodacom site and resubmitted the debit order option once more - the earliest option for the debit order to go off was for Friday 11/03/2016. I duly submitted the Debit Order and waited. The 11/03 came and went and by today (14/03) the Debit Order has still not gone off. There are sufficient funds in the account. I have repeatedly phoned customer care who keeps referring me to the accounts dept, the accounts dept is unreachable via the phone. My emails have been ignored.
