Who called from 5015157201

Robot call saying I had stayed in one of there resorts, sorry scum bags your number is blocked now. I have something for sale on Craigslist, or I wouldn't have answered it in the first place. These people should have their own phone's called everyday like they do our's. Worthless

I think they just have a list like this
501-100-0000
501-100-0001
501-100-0002
and so on from there

Received call on my cell at 12:46pm 3/30/15. When answered, recorded message said "Congratulations! You've been selected for a free cruise to the Bahamas," and I immediately hung up.

I don't EVER callback to a number I don't recognize. especially if they dnot leave a message.

I got the same number show up on my caller ID (I leave my vm off because it seems that all my calls are bogus), but it is labeled a cell phone number.
