Unhappy Customer Experience

I regret the day I agreed to upgrade to Explora 24 moths PriceLock, The pricelock revision has over debited my account, I've called & sms their query channels, all i seem to be getting are reference numbers accompanied by the statement "someone will call me back within 24hrs, but nothing happens, It seems like Multichoice dont care about their customers, once you've agreed for them to debit your account, they do as they please with your funds, when you calling for complains, noting happens. I might be the first person writing this review, but believe me its going to be read by thousands people, hope your business can handle this kind of publicity. the only choice i'm left with now is to reverse this funds, cut my business with this organisation & move on... sad!!!
