Disgusting service and company Vodacom, get your act together!!!

I'd like to know where to report a business. After my last post Vodacom again called trying to make it out to be my fault, despite me having a R0 statement and authorising any due amounts to be deducted via debit order on my expired contract. As they were not helpful I went to the Tygervalley Vodacom store and asked to pay. The cashier could not find anything due. After insisting and giving any reference / details I could think of, they picked up the amount due on their side, which I immediately paid in store in FEB. Two months later and I receive a summons letter. *** Vodacom get your act together!!!!!!! Disgusting service and company.
