DSTV terrible service, don't honour sales promises

Terrible service, after being a client for 15 years on their premium package I was offered a two year lock in deal. I was promised a package which I never received. I asked the salesperson to clarify everything they promised me and double checked ALL the details before agreeing to signup. I have now been charged more than I was paying originally for a lesser package. I have phoned the call centre, chatted to their online chat assistant... even spoke to Darryl Bailey (a manager/supervisor) who promised to call me back the same day to rectify the situation. I have asked them to review the recorded sales call and escalated the issue through all the correct channels with no joy. I am now at the end of my tether. I googled for solutions and came accross all of these terrible reviews for DSTV on hellopeter. It seems that you have to complain on public forums to get any kind of response from DSTV? Well lets see I am not holding my breath.. regards Marco
