SD PVR to Explora trade in

Our SD PVR has rebooted several times during our viewing time. I am not sure how many times it did it while the TV was off. I was advised to upgrade to the Explorer with the options to install 2 Explorers to have what my 1 SD PVR decoder can do. The cost is astronomical. About R2k to replace what I have now. I find it ethically wrong that with our customer laws in place DSTV is allowed to act in this manner regarding the force of hand to be able to replace what we had. If I had insurance on the decoder they would still only replace one - not install and replace both to put me in the same position I was. Now I have to purchased one Explorer at the Randburg Walk-In Centre with the installation fee fully paid on 10. November 2017 and I am still waiting for the installation to happen and till now I don’t know when this will happen. I was told the installation will be done within 48 hours, however I am still waiting, and no one can give a clear indication when this will happen. I was given the run around the whole day today and was finally given a number for Field Services but no one answers the telephone there.
