Unexpected charges from Nissa Car Rental after return — what’s the best way to challenge them?

If Nissa Car Rental charged unexpected post-return fees, review your rental agreement, final invoice, and any fuel or insurance terms to confirm what was contractually allowed versus what was charged.

Collect supporting evidence such as vehicle return photos and official check-in timestamps.

Document everything and contact customer support in writing, clearly requesting a detailed fee breakdown and a reversal of any unjust charges. Make sure to keep records of all messages and response times.

If you don’t receive a satisfactory response, escalate the issue by sharing your experience or filing a complaint on Xolvie to connect with other customers and seek additional support.
