Worst service

Worst expirience got a car in midstream branch. They did not make us aware of a fault in the car. The next day the car already had issues. We then cancelled the contract gave them the car but the bank still deducts money for a car we dont have. They sent no communication of cancellation and did not communicate... Up to date the manager dwayne at midstream branch dodges our calls and messages. I need proof of cancellation for the bank.
