BAD service again and again and again

Another shocking experience with this company. 2 phone calls and over 30 minutes on the phone to remove an old HD PVR decoder and replace it with a new Explorer 3B Well I am still waiting want to load it on the DSTV ( MY) app but even my account number is wrong on the place to add a new decoder so it will not load !!!!!!!! Then on top of all of this, "My system is very slow" So phone me back " Yes I will Sir" NEVER HAPPENS !!!!!!
