bad service/ cant solve problems

I am not pleased with the latest service received from City Property. I stay at one of their Flat in JHB CBD Castle Mansion and it has been two months that our DSTV hasn't been showing certain channels and when I reported the Building manager told me about options to switch to a package lesser than the one I have. this is wrong as they never gave any deadline day to fixing the matter in hand instead they expect us clients to change the package we like to accommodate what they cant solve. The dstv port that all their flat have seem to have lost signal for certain channels and in my flat all tenants in my floor also suffer the same. I am not pleased with this
