MTN and MONDO have been *****ing from us for 8 months

In January of this year my husband got a call from a company called MONDO offering him (what seemed like) a fantastic deal for cell phone data. He checked with the sales lady several times to make sure that it was exactly what we were wanting and she assured him it was. We could choose which service provider we wanted and we chose MTN. We opened the account, our SIM card arrived and all seemed well. The first month was fine, we were careful with the data as we weren't sure how quickly it would run out - watching movies, you tube, internet etc - and it lasted till the end of the month. The next month we were a little bit more relaxed, but still careful, and about halfway through the month everything stopped working. We gave MONDO a call and they informed us that certain parts of our package had run out but we still had 20 gig of Netflix data available. And this didn't seem to be the case anyway as Netflix was also not working. This was the first time we had been told that the deal was broken down into "parts". A certain amount for internet, a certain amount for facebook, a certain amount for Netflix (the sales lady never asked if we actually subscribe to Netflix) etc etc. This is not the agreement that my husband signed into. We put through our complaint, they said they would have to check the recordings. They assured us they would contact us to let us know the outcome, a whole month went by, another payment was taken from our account so we called them. "Oh no", she says, "someone should have called you. We ruled in your favour and the contract has been cancelled!!!" Great!! The next month MTN took their R300. We phoned MTN they looked into it and assured us that they had seen the cancellation and would sort it out for the next month. (no mention of reimbursing us the money, of course). IT IS NOW SEVEN MONTHS LATER, WE ARE STILL BEING BILLED FOR AN ACCOUNT THAT WE WERE **** TO ABOUT, WE WOULD NEVER HAVE SIGNED INTO, AND WE HAVEN'T USED FOR 5 MONTHS. I cancelled and reversed the debit order with my bank last month - so what do MTN do this month? Instead of giving us a call to find out why we had done this they simply took double this month. Now one of my other debit orders (my Medical Aid) has been reversed because there was not enough money in the account (so now I have to waste my time and money sorting that out) and my Bank has charged ME R115 for the fact that this has happened. Never mind the R2400 already spent on something we cancelled and haven't been using, and never wanted in the first place. WHAT ARE YOU GOING TO DO ABOUT THIS MTN.

Oh and the irony, MTN phoned last week to find out how we were enjoying our data contract!!!!
