I don't know this number and when I pick up the call no one answer this is happen may times

It is a Fax # for Hyatt Resort. They weren't soliciting anything, they had been trying to send me a reciept, and had my phone number as my fax number.

They call me all of the time and all it does it beep. It call me from 6307 6305 and 6302. It is driving me crazy. When I call the number back the line is busy.
