I have two decoders one was a compact and one was family view, and i paid them on the 20th of June, towards end of June i contacted call center to upgrate the other one to compact. They upgrated and told me i have to pay the amount of R465 something by 2august. I recieved sms that i have outstanding payment by 7th of July. I make a call again to ask why because they said by august, and the lady said no i must ignore that my payment is due in august, now they blocked one of my decoder and i called again they say i should have paid by july that amount. I wouldnt have guessed that i should pay by July and now they just block the one that i ddnt upgrate, they block the one that i have is been a comact, i feel very furious and the consultants are ***********, i just feel like disconnecting all my decoders and move to another service providers and pay people that knows what they are doing, we pay alot for useless channels and yet they treat us like they dont need us.
