Took off dubble subscription in one month

They deducted double my subscription for the month. I contacted the service centre, after holding on for 8 minutes I spoke to a lady. She confirmed that R799 was deducted to many off my debit order. I asked her when can I expect that money to be paid back into my acoount. She had no answer, but said she will phone me back with a answer. After 2 days and no reply, I contacted the service centre again. Same storie, the lady said that she will get back to me, that is after a conversation of 21 minutes. After a week I went onto the website and logged a call to ask that someone must please get back to me. This afternoon I called the service centre for the third time. After holding on for 9 minutes, I got through to a lady called Primrose. She again confirmed the surplus amount that was deducted. I asked her when Multi Choice will pay it back in my account, she said she will ask her accounts department. After 17 minutes of holding she came back to me and said I must phone this number, *** and they will be able to tell me. This number does not exist. THIS IS REALLY BAD SERVICE. ALL I WANT IS FOR SOMEONE TO INFORM WHEN THE MONEY WILL BE PAID BACK INTO MY ACCOUNT.A.S.A.P.
