POOR OR RATHER NO SERVICE, I WANT MY MONEY BACK

I had registered for a superflex plan on Monday at 10:27 and R299 was taken off my bank account as a successful purchase. I did not receive the service and the plan was not activated but my money was not returned. I have tried calling, the 083135, 135, and *** to report the matter and I have not received help. The consultants say they cannot see my payment and they will escalate but they don't get back to me. I want my money back please because this is *****ing, the agreement has not been met and there is silence from Mtn side. This is appauling!
