Poor customer service, lying to their customers.

Dstv phoned me for the Price lock special that they had going. Intrigued, I phoned back to hear what they could offer me. Firstly I already had an explorer with another decoder in my room and my son had a Lit box meaning he could watch DSTV through the App on his TV but still I wanted to hear because of the additional explorer then I would be able to put it in my bedroom. This was explained to the lady I spoke to, and I mean thoroughly. While going through the whole process she repeatedly told me that I would only be paying R899 for my 2 Explorers and additional decoder for the full 24months. Sounded like a good deal and again I asked her are you sure and she said yes that is what I would pay R899. Since I signed up for this 2year contract I have been paying R989. When I phoned in they explained that it was because of the additional decoder I have so I am paying for the extra view basically. Which I do not agree with because I explained to the lady that I have a Lit box, yet she assured me that I would not pay more than R899. I have phoned someone said they would dispute it and phone me back but to no avail and then last month they deducted more because apparently it was a system error. This is not the first time that this has happened also. Do you guys think that we just have money lying around so you can deduct more than you are suppose to?Would get back to me within 2 days, still waiting spoke to Thabane. I am not a happy customer, I have told you that you can come and get your Explorer because it was sold to me falsely, you basically **** about the price that I was going to pay. I expect someone to give me some feedback very soon because I am not going to let this go. You suck when it comes to customer service.
