unsatisfactory performance by Multichoice

On the 15 August i erroneously overpaid Multichoice account. I paid R6 490.01 instead of R649.01, ever since the 15th i have been requesting my money i am sent from pillar to post. My account number is ***5 and the ref number was given is ***1. And every time i phone they keep on saying the refund has not been done even this morning im told its not. The documents they need to do my refund have been sent long time ago. it is even worse now they claim the mony to be paid to my account has decreased from R5991 to R5814. basically they are not intending to send me my refund until all the money is finished.

Very very disappointed with them. Hello peter help me get my money back please
