Complaint Review: Priceline.com

I made a online reservation and paid for a rental car to use in MI. Priceline already charged me for the car, $185.38, then Avis charged me 145.12 for the same car. Once I seen my statment I called Priceline, they said there are no refunds and that Avis would have to cancel. I said, you charged more than Avis did, the customer service rep said that price I got from Priceline is not given to the average customer, yet Avis charged less. They also told me it was for a SECURE reservation, obviously it was not secured!!!!!! This company is a fraud and is overpricing customers. Now, they need 10 days to investigate and call Avis to verify that I rented a car during business hours. Priceline is trying to make Avis do the refund even though it was $40+ dollars cheaper. I want a refund from Priceline as this company are crooks and thieves!
