I am constantly getting hang up calls from this number who or what are they

I don't know how these people got my number, but they've already called me 5 times today. Of course I'm not going to pick up an unrecognized number, and certainly not one that doesn't leave a voicemail. If it was that Important, they would let me know. So I will continue to ignore these calls.

They are debt collectors.

I'm constantly getting calls from this number & they leave no message; who the heck are they and why don't they have the common sense to leave a message?

I have recieved the call everyday for the past 2 weeks- always at random times. I picked up the one time and they were extremely rude when I told them "Allie" was not available and would not give me the details. They are most likely not debt collectors because they would leave messages.
