Just Plain *****ed

It has become clear to me that Multichoice does not give refunds even if they are at fault, when they overcharged me they credited my money back and asked me to repay it again, some one should audit Multichoice just to confirm if they are not doing this on purpose as some kind of ****, I had to switch from Premium channels to Compact so I can pay them back twice for their mistake. Even when I gave them a bank statement proving my case they said their system contradicted my bank statement so I must pay them back after a while a gave up because phone calls are expensive and I think they count on that
