I purchased tickets through Priceline.com. I did realize that to some degree there were no refunds but I didn't realize that you could not have changes made. I was checking on the status of my ticket through the airline carrier Delta to make sure all of my plans were as stated in my itinerary that Priceline.com sent me. Let me tell you, I was speechless when they told me that the reservations that I had made were canceled on Delta's computers. I spent several DAYS calling trying to get things taken care of. In the mean time, I needed the flight changed leaving from my destination a day sooner. The Customer Service Personnel told me that since I have had all of this trouble that when she figured out what had happened to my tickets being canceled that she would change my departure date to help make up for all of the trouble I went through. After I received no calls about anything dealing with the problems I was having, I called Priceline myself and found out that the tickets had been reinstated but the departure dates had not been changed as was agreed. I then called Delta airlines to make sure that it was reinstated and it wasn't. They had no record of a reinstatement. I tried getting a refund because I was tired of all of the hassle and even let them know I was turning them in to the Better Business Bureau and contacting my lawyer. Regardless of what I said, they did not care. They basically stole $250 from me and did not care. I believe that Priceline is the scam of century. I just can't believe they are legally stealing from people and nothing is being done about it.
