506-236-9019

Junk fax from The Toner Doctor. They filled a sheet of OUR paper full of printer ink makes and models and prices, so they really wasted as much of OUR ink as they possibly could. Had to look up the call history in our Comcast Business account and then blocked the originating number (although it's probably been spoofed and they'll just use a differed number the next time), and their callback number 800-950-5920 (which I see also has a thread here).

Read the post by Pudge in that other thread (just above your post) for information about where to report this company and other actions you can take against them.
