Disapointed and angry

I am so angry and fastracted with Multichoice services I always pay my account before the 1st of every month not even once my DS was disconnected because of my account being on areas.I made a payment of R524 on 27October few days after I received a call from Multichoice saying dat they was a payment of R524 made in error on my account by someone who asked them to reverse it that was a shock to me I told the lady who called me that no ways I made that payment on my account on the 27 October she said there was more then R1000 rands on my account.Ok I said I only paid R524.Than she said she wanted to inform me about the error payment before she do a reversal and I clearly said to her I hope what ever u are doing won't affect my account she said no it won't she will only reverse one R524.Now my DS is disconnected they say I'm owing R454 rand because all the money that was paid in my account has been reversed.Reversed to who or to where I cannot get an answer nor the help.Now whos faulty is all this now I have to safer because of someone's mistake and stupidity.This is total unfair and anaccaptable.
