DPP special - no installation, paying twice!!!

We signed up for the DPP special advertised on DSTV. We were given a number for an installer to call once the explorer arrived. When we called the number, there was no response, it also turned out that it was an installer in another town (even though there are several multichoice approved installers in our town). We were then told that we were likely to have to pay for the person's travel despite installation supposedly being included. Since the installer's number did not work, I tried to google them and apparently they don't exist. I have called DSTV several times and I keep being told that DPP is separate and that I cannot talk to them directly and that they will pass on the message. I never get a response and we are paying for 2 contacts now!!! I also cannot return it because I cannot contact the DPP people!!! It seems that DSTV is using this as a **** to either have people pay for two contracts while waiting or to give up and pay for install for it yourself despite the fact that it should be included! AVOID THE DPP SPECIAL AT ALL COSTS!!!
