Rental Over extra unprofessional transactions

Hi Avis

I am very unhappy, I rented a car and paid R7800 and the total amount due to Avis was supposed to be 5101,98.

To my surprise this morning, instead of receiving the change fro the total money due to Avis rental, I found a debit order and every money I sent to my savings account is been deducted outomatically,

This is affecting me very bad, my fanncial record too, I am struggling to use my account! I want my money this is unprofessional.
