1/26/11 - I received two calls on my Cell.  The person indicated that message was for …… (name given was my son.  He never gives my cell number to his credit card company so I was suspicious) and the person indicated that three airline tickets were charged to my credit card and I need to call them immediately.  He gave me a reference number and emphasize that there were four tickets charged (obviously, he never keep track of how many tickets were charged).  I called the number from my home phone and the message indicated that they are busy and I am supposed to leave name and telephone number.   Please DO NOT call the number nor give any other information including their reference number.

Got two voicemails from 203-441-8454. FRAUD. Man spoke with Indian accent and claimed to be from the Kayak Fraud Prevention Department. He said that he needed to confirm some information about my method of payment and asked for me to call him back on the same line and to have a certain case number ready when I called, which he read off to me in both voicemails. He called around 10pm both times, which set me off right away. The first few times i called back, the line was busy. After he tried again a few days later, I called back again, but i got the voiceail and the machine said that the voicemailbox was full. I have received no emails indicating that anything is wrong with my flight or that anything needs to be confirmed, so it seems clear to me that this is a SCAM. Priceline, Spirit, and Kayak--stop making info available to these people!!! Won't be booking with any of these sites again.

got a call concerning fraud for tickets as well.. looked into it and also called credit card company first to make sure no issue was real.. incase it was fraud.... which is what it seems to be.
numbers are 203-441-8454
203 741 8454

I just got two calls from the above mentioned number as well... except they called me at 3:02 AM...yep..3:00 AM !!! I knew something wss wrong because he was a man with very bad & llittle english. He went on to say he was from Priceline Fraud Prevention. I simply told him Ive never used Priceline & do you have a clue What Time It Is in the United States????  He hung up.... You would think if there gonna try n scam they would at least know what time it is here in the good ol' US of A... just sayin.. lol ;)

I had the same the same thing happen to me last night.at 3:00 am. Same Indian accent I just hung up. Well today while checking my online accounts there it was 2 charges on my credit card one for Priceline and another for Starbucks, I called my Bank Card right away and had my account closed. I will be keeping an eye on other accounts as well for they are still calling my house. If you have credit cards that you don't use often keep a close eye on them, it seems those are the ones they seem to be targeting. I called my credit card companies and gave them all the heads up. Really considering Life lock after this one. Its pretty scary. :(
