DSTV ARE A BUNCH OF ******!!!

I am on compact package and I signed up for 50GB for R499 x 24 mnths. Today they send me a msg that I have been topped up with my 25GB allocation pm. That is not what I signed up for. I signed up for 50GB that is what the package showed. Why are they giving me 25GB if I am paying R499 for 50GB. Both the Family and Access packages are 50GB. I am on Compact and I get 25GB for R499 that's not what I signed up for. Bunch of ****** if you ask me. It's never smooth sailing with DStv always a damn problem with them.
