Debit with no approval of the cover nor receiving contact

Old mutual debited my acc, I never received any contract I was Enquiring online and an agent was to call and confirm but nothing now they debone me there’s no contract nothing. Please refund my account immediately and cancel whatever you put on without my consent . My cell is *** Bathobile radebe I’m sure you will get my details with my number. I need my money cancel that and send proof of cancellation. You can blacklist me from your services. I’ve lost so much money in years with old mutual always cancelling my plans after 1 failed debit I don’t want anything to do with you guys. Even my child educational cover was cancelled never got a dime and now this no thank you
