I got a call from this number and they left a message. It sounded like and old lady and she was calling who she thought was her grandson. I tried calling back but immediately got a dial tone

This number is simply a system access number for Distributel Long Distance.  It could be anyone from the Kitchener/Waterloo area who is a Distributel Long Distance Plan customer.

hung up without replying when I answered

It's just an access code number for people who use Distributel long distance. It's probably just someone you know.

THIS NUMBER called my home phone and the caller ID said" DISTRIBUTEL". I did not answer and then immediately afterward my cell phone rang and just showed the same phone number.

hi pat hope all is well tried to call you about your mom, please call me
