JJF: Me too! No unpaid bills either! This number is beyond annoying. Just blocked them tonight. Go away!!!!

I got a call from this number too but they are unable to speak. Nobody can do anything against these guys?

As far as I can surmize this is a automated calling machine ( typically looking to scam the un-expecting senior ).  Government SHOUD be on this!  But as per usual the 'free-market' outstrips any kind of descent moral behaviour nowadays!

I just got a call from this number and I didn't answer but when I called it back, it says I've just dialed a number that is not in use.

Calls from this number come in but there seems to be no one on the other end. Calling the number back produces the message that the number is not in service.
P.S. I don't have any unpaid bills!

It's a company called Allied International. If you've received a call from this number, it's because you must owe some credit card company some money.
