Here it is Jan 2011 two years after the first posting... and Mass Media is still sending out multipe faxes, I've tried calling the do-not-call numbers but it is constantly busy. Why can't we get these folks shut down?

We have to stop these faxes it is costing a fortune in ink and paper and there should be a law against this kind of advertising. I have called Mass-Media Inc  4 times to get my fax number removed and I just received 3 faxes.  So now I call the advertisers and tell them to remove my fax number and that I would never deal with them because this kind if marketing is unacceptable. If advertisers do not get results only complaints maybe we can stop this from happening

Just sick of getting un-solicitated faxes, I've tried calling, but just get answering machines.
I 'm still investigating, and will have them charged when I find who the owners are.

Well, I'm late to this party, with faxes just starting lately. Boy, what a pain. I've called and called. I also let the companies know I'd never use them due to this.I put our number in the do not call list, but from others' experience this will not work.Argg...Rob

The number (416) 907-7555 advertised as One Stop Professionals will not receive a "blocked" "*67" call from you.  You must disclose your identity to complain as the other number that is on the junk fax (416) 800-1106 is difficult to reach and may yeild the same response.In reaching the (416) 907-7555 person they indicated the owner was Andrew Brews at 13085 Yonge St. Unit #111.  The actual business name would not be disclosed.  If you get it maybe Revenue Canada should be notified about the number of different "company names" are being used to ensure this person is paying his/her fair share of taxes. There are a number of units at this location as indicated in a Prophone CD 1997 however a reverse search from canada411.ca yeilds no address found from the associated postal code L4E3S8.  I will try Street View by Google to get a better picture.May I suggest trying other ways of identifying who this person is as they seem to be able to get unlisted phone numbers as in my case.  The best avenue is to try and reach them and stop the replication of your number and threaten to send him a bill for tying up your fax machine line.  better still use this site to indicate who these people are so that others can decide how to deal with the situation.  These telemarketers make a ton of money and the number of people who hate these calls is growing.  Good luck.
