Rentalcars.com is hiring cars for companies which do not exist in real life. Just came back from holidays in Poland. Rented a car through RyanAir which is redirecting to Rentalcars.com. When arrived to airport in Poland , I have tried to contact person which suppose to meet and greet us. Call goes straight to voicemail. I have left message and had call back from different number than that I called. Guy said that he has nothing to do with car hire company.I had no choice but to hire a car from different company. I have contacted RyanAir which directed me to Rentalcars.com I have contacted Rentalcars.com. They responded and said that I cannot have refund as I didn't cancel my booking. How could I know that car hire does only exist on the web but not in real life. Rentalcars.com shouldn't even receive one star. It is the lowest of the low. They do not check even if company is existing and they keep on selling product.
