Over charged by dstv

So, a few weeks ago I received a call from a nice girl at Multichoice, she wanted to offer me a "free" DSTV EXPLORA as I was such a good and loyal customer. Of course I agreed and I did understand that in fact I was signing up to dstv for a further 2 years in order to get said "free" product. The EXPLORA arrived and then a installer came and installed it, for free! All good so far.

Then came the 1st of March and by debit order was taken. I was over charged a total of around R1300 on my bill (to most this is quite a bit). I called and was advised that my subscription had been duplicated so that I was charged twice (pro rata as well) I was told I would be refunded and all was sorted. A few days later I noticed that one of my subscriptions was no longer working, I called dstv again and was told it had been cancelled!!! Why? nobody will ever know. The subscription in question was then re-activated and I was assured I would have my refund by the end of the week at the latest. It is now Monday of the following week, 12 days since my initial call and no refund, I have called again this morning and have been assured I will be refunded by Wednesday.

I am not at all happy with the service from DSTV/Multichoice. I didn't ask for the EXPLORA you called me!!! As a result I have been R1300 less in my account for almost 2 weeks, you don't know what effect this may have had in my life and clearly you are not interested either. I have spent a small fortune on the phone to you people trying to sort this mess out.
