I didn't want   waste my time and late him talk to air  .....

Or they are also possibly calling over the internet with a VOIP service. This can also generate telephone numbers in the caller id that can't be called back because they are not valid telephone numbers.

They are calling you from a working telephone number...but they are transmitting false caller id information to hide their identity. It is called caller id spoofing.

if you try to call it back it says the number is incorrect so how are these people whoever they are calling us from a number that isnt even working.......When the call comes through it has a additional 2 0's on the end

I'M GETTING CALLS IN THE MIDDLE OF THE NIGHT FROM THIS COMPANY

Called 3 times in a row, each call was within 5 minutes of the previous one. No message. Nothing on the caller ID except "Unknown". Very creepy feeling like I was being watched screening my calls.
