Very Bad support from Home Connect.

I've been asking Home connect to come to my place to sort out my internet since January there. I joined with them end of the year in November last year and since then I realised that as much as I have a 20/20 speed option, however it is worse than when I used to have a 10/10 from a different service provider. In this house I can't watch two things from our lounge and also in the room at the same time. One must stop or else one will be buffering and all. I pay these people around R800 for that, honestly it is rather disturbing, cause this is tiring now. Every month they are good in deducting amount from me, but no support whatsoever. When I call I wait forever for the support to answer the call. I am really tired of their poor service.
