Debit ********

My husband is renting a car from why buy cars, this is now the second month that he is renting from them. I received a mail that the car must go for inspection and then he can make a payment there. He then notified them and told them he have a lift at work and will not be ablw to bring the car after 12 but he can make the payment via eft and bring the car late or the next day. They said no problem then you can pay the car. On arrival the next day we paid extra and paid R5000 with card. Sat. I saw that a debit went off from my account it was taken by webuy cars woodford. I have mailed, called all the numbers. My other debit orders was unable to go off because of this. It is now monday after 12 and still not one call mail nothing from them. I would like to know how they can just take money out of my account. I have not signed a contract with them, nowhere did I give permission for them to take any money out of my account. Tonight my other debits is going to go off again. I pay extra because there is no funds in my account. A guy at the cape town airport provided my husband with a number on whatsapp, he have send his id, proof of the debit order and he told them that it is not even his account that they have debited but still they took the money. What must I do regarding this matter? Who is going to pay the extra bank fees that they are costing me now and how long must i wait for my money that they took out of my account without my permission?
