Who called from 2054024775

Called it back and got "number is not in service".   Will research how and who to lodge a complaint with.  Caller ID said "Birmingham AL".

They keep calling our house too. When I call it back it says the number is not available.

Got a call from this number.  It looks like a cell phone number (but who can tell these days), the caller ID shows Unknown name.  Why is it these people won't let you know who they are or they won't leave a message.  Are they ashamed of themselves?  It's ridiculous.

Caller ID is "Birmingham, AL". Called back and it says "The number you have reached is not in service". A telemarketer perhaps?
