It is a company called "JUST ENERGY" .Seems like a scam. I have all inclusive rent and there is no reason they should be calling. Ignore and don't call back.

Have been receiving phone calls from this number and it is Just Energy.  Had an account with them which I canceled. Was originally told I had a no fee cancellation because I am over the age of 65.  Now they want $50 for my cancellation.

I recieved the same type of message several times. I finally called the number back and it was a company called "Just Energy", a third party supplying gas and electric to residentual houses. I had an account with them and had to cancel because I moved but I always thought the company was sketchy.

I just received a message from this number asking me to call back about an "important personal matter."  The voice was a computer, no company name was given, and the message included a number for me to reference when I call back.  Sketchy!!
