Something to do with the airline service CheapOair. I tried to book a flight through CheapOair, and it didn't go through because apparently someone got the seat before I was finished booking. About 5 seconds later, this number called me 4 times. I don't answer calls from unidentified numbers, and this is part of the reason why.

caller did not identify himself told me that booking company was not accepting the agreement with the airline i then heard laughing and stupid jokes, so I hung up, called back this goes directly to a tape saying that this number is not accepting calls at this time.
