DStv Robs me daylight

I am so tired of DStv finding pleasure in making my life miserable by double charging me . This is happening for the second time where there are additional charges and not even your agents can explain to me they tell me because I have added a new decoder which is a pvr then there was an access fee of R60 and R105 but how can this be charged twice. Your stuff is so uninformed and it's not even funny that we are being ********** while nobody can answer the concerns brought forward. I want to know why I am being an access fee when my package is active and what are the above mentioned charges for? Does buying a Pvr see decoder exposes one to being ****** daylight?
