Stole money out of my bank account

Multi Choice debited my Account for R635 without my consent. According to them in 2018 a payment from me to them was reversed. I did not even have a subscription with them and in the time I did have a subscription I paid cash. I do not even stay in South Africa anymore. So there is no way that can have dstv. So in other words thay stole me money right out of my bank account. Wonder howe many people this happened to. Every time I email I just get another story. I called multi choice in Bloemfontein thay say thay can not see any payment or outstanding payments on my name. Makes you wonder. Jan
