Calls my land line incessently. What can be done to stop these people?

keep calling after I contacted them and notifie dthem they are sending junk fax to my cell phone.

in the last 2 days i have gotten over 15 calls from (416) 847-1150, i have been getting calls from this number for over 2 years, they sound like they are comming from a fax, i have tryed to find out where the call are comming from, but have not been able to get that infromation. i just want the calls to STOP!!

As i finished the last message I rec'd another!

Used the instructions to stop  this annoying fax machine calling my business line.  Hopefully it will work !

Day in and Day out! this is only one of the many. I tried the instructions above, so we shall see how long it takes to work. This is My sole business line so it is important that it is not hogged by these stupid fax services. Not to mention it has never in the 5-6 years I have had it been a fax line.
