I received a call from this number today 7/22/07 at about 7:30pm central time (Austin, TX). It was quiet on the line for a second but I could hear noise in the background like people talking, and then there was a beep and the call ended. I hope this doesn't continue.
I received the same call today from the same number and same call back number. I didn't bother calling them back though figuring it was a scam, since 1) they didn't mention my name and didn't say were I entered. (so assuming they didn't know either); 2.) they didn't give a bunch of information about themselves. (no website that i could find) and 3.) i don't recall ever submitting an entry form for a jeep cherokee.
i received the same call today. same number, same call back. pre-recorded voice message detailing that i didn't win a jeep cherokee, but i did win a 7-day cruise to cozumel leaving from galveston.
