Hello world of Reddit, and particularly CAR RENTAL AGENTS!!! I need some feedback before I attempt to call Discount Car Rentals to discuss the issue, I wanna have my knowledge guns loaded before I go in there blazing.

First of all I'm in Canada.

Backstory: rented a Ford Fusion last weekend to go camping out of town. Rental was for 2 days, came to $91 and change for 4000kms, just had to fill up the gas tank before return, salesperson said that's it and that's all, you'll only be charged extra if you go over the kms, (which I certainly didn't do) enjoy your weekend, goodbye.

So I paid the $91 and change which covered basic insurance, 4000kms and paid the $400 deposit which they said would be credited back to my card early this week. Just checked my account, Discount charged me $271.00 !!!!!

**WTF?!**  $271.00 > $91.99 What could I have possibly been charged for?! We didn't smoke in the car, that's the only thing I could think of.
<bot>: Discount said pay me $91 for a rental, checked my Credit Card and they charged me $271.00 !!! WTF?!
