I have gotten calls from this number also. THey do not leave a message. However if they are the inquirer I get the paper four days a week and there is no reason to call me and I did actually at one point get someone on the phone and told them to stop but obviously they are not stopping..
I said "Hello, Moe's Bar. Moe Syzlak speaking." They said nothing. Then I said "You'll have to speak up, I'm wearing a towel" and they hung up! Imagine that.
