*********** and lack of customer service

I lodged a SR*** with vodacom since they billed me incorrectly. and the lady who assisted confirmed that the bill was incorrect and seems to be an error. to my shock on the 25 the account was debited and still no one has said anything to me or responded to my query. every time i call am send from pillar to post, and still to this day a month later no one has helped me. everytime i have to request something or service from Vodacom, there always has to be some drama
