I rent a car thru Priceline and I was suppose to pay 249 dol. the bill ended on 530 dollars , the agent Told me that I was going to be credited for 200 plus when The car was returned, I found few days later that he was charging me for supplemental liability ( I told him from the beginning of the rental process that I did not need it. I also had to return the car after 2 days because the engine light came out.
