DOUBLE DEBIT ****!

Got debited twice in October and logged a call. I was asked to send my bank statement as proof which I did and I got no response. I called and I was told they can't see the double debit on their side so I resent it and still got no response. I then sent messages on their official social media pages and was told someone would call. No one did. Had to call them again and this time the lady I spoke too said I had a credit of R499 and asked if I'd like it to be refunded into my bank account or credited on my rain account which I said I want it in my bank account then she went on to say I'd get a call from the refunds department so that they get my details. Instead I got an email saying the was no double debit yet I provided the proof. In November I still got debited and I bet they'll debit me in December as well while not taking into account the October double debit and I've never missed any payments. Rain are **********! I'm currently looking for new credible service provides
