I am reporting a serious issue…
I am reporting a serious issue regarding my recent Avis rental at Heathrow Airport (T234), booked via Check24 (Germany), which included zero-excess insurance.
At pickup, I explicitly declined any vehicle upgrade, additional insurance products, and fuel/refuelling services. Despite this, these items were included in the final contract and charged to my account.
The contract was processed very quickly, leaving no meaningful opportunity to properly review or reject the additional charges before signature.
As a result, I have been billed for services that were not clearly requested or agreed to. In particular, an upgrade charge was applied, despite no upgrade being received or used. The vehicle was returned with a full fuel tank, making fuel-related charges unjustified.
I have already contacted customer service, but the issue remains unresolved.
I am requesting a full review and correction of the invoice, including removal of all disputed charges and issuance of a corrected bill reflecting only the base rental.
At this stage, I consider the billing process misleading and not aligned with the expected standard of transparency.
