EXTRA CHARGES

I am very annoyed by what Dstv is doing - i am not too sure as to what business they running and how many more customers like myself they have . In jan changed my payment date to the 27th of every month and for the past few months they have been charging me for subscription fee , i would pay this money until i made a call again to them to informed them that you are extra charging me , i pay my account on time why charge me extra when i pay on time - last two calles i had lady helped me with the issue and promised this will never happen again . Today they have again stopped my viewing , called again gave same story now have more than 150 to pay for what i dont know as i again always pay on time . the lady said i must hold , i held for so long she never came back to me and again i am not assisted . this is surely what they do to customers , they add these extra fees so we can have our line back even when paying on time , so unfair !!!!!
