They called my phone and didn't leave a message.  I googled the number and came across this thread.  Thanks everyone for posting as I know now to ignore them.

HAHAHA and eternity it will be!

(905) 296-4992 aka MYRON who sells products like calendars with your engraved name on it, is a f**king pest! They call my business all the time and I press the # sign over and over and hold it down...so it calls back automatically and pissed the guy off. It is a scam call which can cost you $ because you get charged. So I figured, if I'm going to get charged, I might as well have some fun.  Well, he called back and he yelled as us and said he was going to call for the rest of eternity and make our lives miserable. He was very cynical.  Unfortunately  there isn't anything we can do, because the number is international (U.S. can't block it).  However, I also learned the number is from Hamilton, ON Canada - and the service provider is Call Net Communications. I did write to call busters in Canada and reported them.
They are such pests!

Received a call from this number while I was on another call.  No message left. Do not want them to call again if they can't leave a message I'm not going to respond and waist my time.

They have called me everyday for 2 weeks. Thank goodness for caller ID. Maybe they'll give up soon.

I called 1-+1 800-526-9766 and requested to be taken off their list....damn company called me every day for the past week.  Every time they call I want to punch them in the nose and say cuss words.
