***UPDATE***

I did a search on this site for the variations of the number and I've found an entry stating that it might be CANADA STUDENT LOAN calling.  I checked with the Canada student loan and they said that the calls are not coming from them.

***UPDATE***

I'm from NB Canada.  I've been receiving recorded phone calls from 1-866 and 1-905 numbers for weeks now.  Just received a call w/ recorded message today saying "Its a very serious matter, it won't go away, call us back at 1-866-something (I didn't hear the rest of it because it stopped)" They never say my name, the reason they're calling and/or the company they're working for.Variation of the number calling for the same reason:+1 866-574-0222+1 866-803-6687+1 866-879-5172(905) 306-6220    thanks in advance

Same as above: Automated message (cut off at the beginning) "-of Canada. We are expecting a phone call in the next 24 hours. This is a very serious matter, it won't go away. Our number is - " (cut off again) Very suspicious. I think the cut off at the beginning is intentional on the part of the caller. I get this call 3-4 times a week. and it's annoying the hell out of me.

I have just received # 9 of these stupid messages...when is someone going to be able to make these stop.  I did answered two calls the other day and one was trying to sell me a platinum card and the other(i'm not too sure)...would let me say that i'm not interested...he kept saying that i would be foolish to pass this up. I had to hang up on him.the number in the message is +1 866-803-6687....very urgent business matter that you must return....etc.
