I believe the rental car company engaged in serious deceit. I had already paid the full amount on the platform because I was worried about being cheated. When picking up the car, I explained to the employee that I didn't want to add any extras since I'd paid in full. Now I received a charge for upgrading the car and a bunch of other fees. I only rented the car for 2 days, but the company charged me much more than my two-day rental should cost. I can't accept this. I hope the platform helps me resolve this issue. Unacceptable! The platform didn't make enough effort to help me appeal!
