This scam apparently originates from an American man who currently goes by the name of Richard Davis. He has been in trouble with the law numerous times and uses numerous other aliases. Two of his biggest sites on the net are for illegal pharmacy sales. How do I know all of this? I saw a real opportunity while unemployed. That opportunity was to hunt down and post the identities of the scammers out there who call 87 year old women at 1 in the afternoon trying to scam them. My site is just about finished and I will post the URL here when it's done. I'm just a few days away from catching this ba$tard. If you get a call from this number, report it to whichever US or Canadian authority you possibly can.
If the call was to your cellphone, try suing them too. Great article on this posted here:

There are new laws being proposed regarding calls like this. I have received calls from them the last few days - no message. I have now blocked the number.
