Overcharge, No response

It is very sad that a giant like Vodacom receives customer query and takes longer than a month to respond or resolve the matter.<br> <br> I have been billed an amount of R2582.85 on my account, normal monthly instalment is R250 which has never been exceeded for data throughout the contract, only calls also by around R50, once in a blue moon. Just for giving notice that I will be terminating the contract at the end of the contract term, I go a bill of R2 582.85. I have never used data exceeding or equal to my monthly allocation of 75 MB, however, after giving in notice of termination, I am informed that my data account was above 2GB which is absolutely impossible considering that I have not switched on the data no use the sim card on a regular bases. I have reported this issue for investigation,14 days was promised, till today, no response. I would like assistance in this regard as this is unprofessional, indicates a poor service and lack of care by Vodacom to attend customer issues. <br> When I wrote this report, I received a response saying this issue will be handed over for investigation a month ago. Believe me, no word till today. Unprofessional, *********** and no care for customer service
