Theft

I have been over charged for a month now on my vodacom account. I have contacted them numerous times to get resolved and they just keep over debiting me . On monday the 18th of Dec I once again contacted them to inform them, they have scheduled an over debit on my account. Numerous calls (from my side, cause they do not get back to me) and a lot of back and forth, but once again no luck. I wake up to a sms of the over debit going off. This is THEFT vodacom!!! Your process of 10-14 days to be reversed etc is nonsense!!! if i missed my debit, my account get blocked almost immediately. How is it right that I have to wait for you to take your time to resolve a mistake YOU made and one that I WARNED you about!!!! VODACOM HAS NO IDEA WHAT CUSTOMER SERVICE IS AND IT MEANS NOTHING TO THEM. THEY ARE JUST MONEY GRABBING *******!!!
