Forced insurance is one of the most common problems in car rentals. If your booking clearly stated that insurance was included, or if the coverage terms were clearly specified, the rental company has no right to require the mandatory purchase of additional insurance.
It is important to understand that:
additional insurance must be optional only
refusing it cannot be a reason to deny the car
pressure or intimidation is considered a violation
What you should do in practice:
show your voucher or booking confirmation
clarify exactly which risks are already covered
document any refusal to provide the car without extra payment
keep all documents and correspondence
If the car is not provided unless you buy the imposed insurance, this constitutes a failure to fulfill the booking terms. In such a case, you should file a claim through the booking service and demand compensation.
A complaint on Xolvie helps document cases of forced add-ons, speeds up refunds, and warns other Economy Bookings users about such practices.
