Been receiveing calls from (646) 224 5943 for over a month.
The caller claims to be from a company dealing in stocks, and that I have some stocks which are worthless.
For some reason he wants to buy these stocks (which I don't have) for 15 times the market value.

I did for fun tell him that I had some other stocks which were not performing very well, and surprize, surprize - these stocks would work just as good as the ones I didn't have.
The only thing I had to do was to pay a fee in order for the forms to be processed - which was 12.000 US$...

The caller couldn't provide me with a valid stock-broker number, he couldn't give me his name of his regulator.

Stay away from this guy.
