Charged me double subscription fee.

I'd had DSTV premium extra view for a year which cost me R799 per month. Sent an SMS for the EXPLORA upgrade. Agent told me that if I added the explora to my existing contract, it would cost an extra R99 pm, However, if I started with a new contract from scratch it would only cost me R850 pm. The agent told me that as soon as the Explora had been installed, I would have to call DSTV to cancel the old contract. It was a nightmare trying to get the Explora installed in Cape Town. I had sent my suburb via sms to DSTV as instructed and two weeks later called them as I had still not received a call from any installer. This is after DSTV had responded to my SMS. This transpired in the middle of June 2015. By the 1st of July, DSTV had deducted over R1700 from my account, before my Explora had been installed. I have called them over and over again having to repeat myself each time. At the beginning of October after yet another call from me, I finally had someone get back to me, however, still no joy. They had to listen to the voice recording (which they have been telling me for 4 months now) and now they're not getting back to me. I'm still waiting for my refund. So Angry now!!
