BAD, DISGUSTING SERVICE AND A *******

I have a price lock for R499, the month of September 30th i was debited the amount of R796.54. I send emails to ask why that amount since one can never have arrears on a prepaid service. I reversed the payment when i did not get any response, i was deactivated, then received an email that says R233.55 was pro rated from period of the contract and R499 subscription. The amounts did not equate R796.55 still, i paid the two amounts. On 29 September they said i owe R2054.88, i called on 30 September to be told i owe R539 which still is not the subscription R499. On 30 September i was debited with R1956.82. WHY AM I BEING DEBITED THESE RIDICULOUS AMOUNTS? The call centre says price lock is outsourced but when we were applying no one said that. I am appalled and want to cancel multichoice price lock and go back to my 4U decoder.
