Hertz Hertz Credit me 2750$ instead of 284$ Cairo Nationwide

Referring to my agreement no 125495381.

I have rent a car from hertz office at double tree by Hilton on 8 July for 5 days. Then I return the car at the same office on 12 July 11:00 pm.

When I return back to my country I found that I was credit my master card by 2750$ instead of 284$. Base on the invoice, the car was rented for 25 days !!!!???

Actually I didn't spend 25 days in USA. I travel from USA on 19 July.
