Charge for data not used

Despite extensive correspondence and proof of non-usage of data - including an affadavit - Vodacom still treats me as a **** and has not tried to refund so much as 1c of the more than R10 000 deducted off my personal account on a company (Via Afrika of Media24) cell phone account. Despite revoking my permission to deduct money off my personal account and blocking Vodacom at my bank, you still found a devious way to continue doing so. After an arrangement between my company of employment at the time and Vodacom that no more money would be deducted, Vodacom deducted another R4 000 plus. Minette Klein from Vodacom has been the only person communicating with me, in a patronising and unhelpful way. Let me know when I can expect the refunf for all the overcharges. Minette Klein holds all correspondence, including my affadivat of non-usage.
