Multichoice denying me access to nice life problem

multi choice suspended my smart card arguing that my account was behind, however the amount that was said to be behind did not tally with logic. i have 2 independent smart cards, in two different locations, one in bloemfontein and other in polokwane. together these two cards cost R1400, on the 1st of august i paid R900 towards my account as my polokwane smart card was active throughout my cycle, which runs from 15th to 15th, of each month. however last week on the 20th of august, sayin i owe them R858, this claims defies the logic. how can i owe that muc when i had paid R900, a single premium is R699, 2 is R1398 to be exact. i caled them on tuesday, enquiring about this bizarre statement, i then learned that i have been charged for extra view and PVR decoding, i dont have both PVR and extra view on decoders, both of them, call center agent promised that my problem was escalated and wil be solved before end of business, it didnt. i call early evening same day, i was given same undertaking that my problem will be solved before \end of ?veving""; i called on thursday;3 superviors promised that my prbm wil b solvd"""
