I kept receiving attempted faxes from this number at work.  I called the phone number mentioned above by "helping" and a nice guy answered the phone and said it was a fax for some workshop, and offered to take us off the list.

their phone number is 403 259 8555, call them and tell them they are faxing you

I continually get faxes on my phone from this number but I do not have a fax.  How do I get them to quit,
