DStv is yet to rectify their mistake

DStv incorrectly debited me R610 instaed of R200. It was a battle trying to get somebody to help. I eventually posted on hello Peter, then only somebody called and advised it was a mistake on their side. She then said that they will credit my bank account within 48 hours. It's now way over the turn around time and I still haven't received my money. I'm definitely cancelling and so will all my family members who have DStv. We rather switch to Netflix because DStv service is pathetic.
