They are a true scam. I bought full coverage with them for a rental car in Portugal, as a consequence I did not pay for zero deductible at the car rental company desk. Unfortunately I had an accident with the vehicle, which led me to pay the full deductible of €1500. I Immediately contacted RentalCover for reimbursement of this value. After they asked for all the documents about the rental and the accident including the receipt of the deductible I paid, they then said they could not reimburse me without seeing the invoice for the repairs done to the vehicle! Of course I didn't have that invoice! this is internal business of the rental car company. In summary, if you buy insurance from rentalcover, you are throwing your money away. To me they are frauding customers.
