Despite renting a fully insured car from Europcar switzerland , agreement number 50873110 with the highest insurance coverage, I faced a serious safety issue due to a faulty satnav that led me over a dangerous mountain route. When I called Europcar Assistance, they failed to respond. I had to involve the police, who sent emergency services to tow the car to safety, costing me 200 CHF. To my shock, Europcar refused to cover the towing charges and provided zero support throughout the ordeal. Extremely disappointing experience with no accountability or customer support
