Incorrect data charge

On 4 August my wife received an SMS notifying her that she had incurred unusually high data usage and had exceeded her data bundle for the month, and it was only the 4th of the month. We immediately contacted the Vodacom call centre who said the matter could only be resolved at the "end of the billing cycle" being 3 September. We were assured the matter would be attended to once the billing cycle was complete. On 7 September Vodacom debited our account for an amount of R9797.46 - 6 times the normal monthly account !!

I have tried several times to resolve this matter with Vodacom who have offered a nett credit of R6 885.87 which is unacceptable as this means the nett charge for the month will be R2 911.59 (R9797.46 - R6885.87) which is approx double the normal monthly account.

It is totally unacceptable that Vodacom can debit a bank account whilst there is a dispute in progress.

Please assist in resolving this matter.
