The worst service

I signed up for a price lock package and then I wanted to change the package the very same day when I tried to call in I got told I have to call the price lock department which I then did I wasted R70 worth of airtime and never got through to them I left probably 3 call backs and I got nothing I emailed dstv probably more than 5 times which I can prove to you guys and now the decoder got delivered I would like to change the package and I would like feedback ASAP or it will go viral!
