Who called from 4056004000

This number called me yesterday and today; I didn't answer and they didn't leave a voicemail. Apparently the number belongs to "Cardinal River Energy" but I have no idea who the heck that is or what they could possibly want from me!

Do not call this number back! They will charge you 4.99. Just got off the phone with my carrier- grrr

I just got a call but do not answer these collection agencies hide behind all these numbers

They did not leave a message, so I called it back, one day.  I had to enter an extension #.  I don't remember what extension number I used, but it gave me another number to call, which ultimately put me in touch with Cox internet.  They could not figure out why one of them might have called, so gave me a sales pitch.  I told them I didn't need their tv service.  I have enough FREE channels and I have their internet.  I don't need any other services, or I would have them.

I would suggest not calling them back.  If you put in the wrong extension #, there is no telling what company you might get.  Game of roulette, if you ask me!

Great, thanks for the info.  Got a call while in a meeting.  They didn't leave a message, so I'll consider it junk.
