Unlawful deduction and disinformation - Consumer Complaint for AVIS RENT A CAR - HEAD OFFICE

I was charged extra one day than being informed telephonically. During the signing of rental agreement. I was never told of rental period in hours. I peruse contract agreement. Neither i could find one day extra charge if the car is return on the agreed date. But not coinciding with 24 hours. Consultant failed to show me where written the agreement signed. I did not sign on vehicle submission due to dispute. My account was unlawfully charged with unauthorised deduction. Please I request for justice in order to have my extra one day refund.
