I have received several calls from this phone number over the last couple of weeks. They call during that day when I am at work, in the afternoon, and I've even received calls from them at 1:30am!!  I don't appreciate this!  When I have answered the phone, they either hang up right away, but there have been a couple of times when I have heard a faint mumbling of voices in the background, but then they hang up. It was starting to concern me. I want to know how they got my number, why they never leave a message, and why they hang up when I do answer. This needs to stop!

This is my uncle's cell phone.  Call him back and ask him.  His name is Dave.
