My balance is R9000 for one decoder for one month

I am fed up with this pathetic *********** services !! Last week they deducted R1800 for 1 explora and sd pvr decoders with xtraview. My account was not in arrears. When I phoned they said it was an error on their side, and I should reverse the debit order, which I did. Monday I phoned back to find out if something has happened, only to be told, I am in arrears and I better pay now. So I immediately paid the amount of R900 which I was informed I should pay. This morning, all my services have been disconnected, and a new decoder has been added to my profile, with a smart card which I do not own, or do not have,and that has been activated. So far they have not been able to remove this decoder, and not able to restore my services. Oh yes and the balance that I owed showed this morning at R0. This afternoon its standing at R9000, with no service. So I phoned and cancelled all my accounts, go get stuffed, I will not pay a single cent . I am done with you
