INSURANCE DEBITED WITHOUT AUTHORIZATION

I have a vehicle financed through ABSA. This morning I go to fill petrol and my card was declined twice so I go into the garage and check and I have no funds in my bank account. I had to get someone to deposit money into my bank account and then pay for the petrol before I leave. I get a statement from the bank and find out that I was charged R1000 extra for insurance that I dont need. that means that I am now paying for 2 insurances on 1 Vehicle. I have been trying to get hold of someone in higher authority from 8:30 am and have been put through from one department to the next. Finally a manager gets back to me with the worst imaginable attitude possible. Valme Flemer- she had no customer management skills what so ever.I have sent through my proof of insurance and have been told money will be refunded in 5-7 working days ! This is unacceptable i will have no money to get to work!!! It was very convenient for ABSA to have my contact details in the past and get a hold of me all of a sudden they dont have my cell number yet i get estatements every month they could have sent an email. I am absolutely infuriated and you cannot debit peoples accounts without consent.!!!!
