Multichoice debits clients without notice

on 28 July 2015 Multichoice debited my account for a monthly subscription fee even though I am an annual paying client and my account was fully paid. On contacting them I was eventually told it was a system glitch as they had upgraded systems and that I would be refunded the amount however the refund is still not reflecting in my account. The account they 'accidentally' debited is the account used to pay my bond and now because of their error I have to entertain an R8 service fee for the amount incorrectly debited as well as put additional funds (which I have to pull out of a friggen hat) into that account to avoid a bounced bond debit which has now also cost me an additional amount to transfer that money over. I want the amount refunded immediately, along with the R8 service fee as well as the fee I have incurred to transfer funds over to that account to avoid an unpaid debit order. This has been a HUGE inconvenience to me and has now left me short of cash and one would think that the refund would of been processed immediately however they are dragging their feet with this. ** HIGHLY ANNOYED CURRENTLY **
