I have just received a 'final notification' letter from 'Loteria Primitiva' saying 'This is to inform you on the release of the International lottery promotion program held on 20th of December, 2008. Due to mix up of some numbers and names, the results was released on the 18th of JANUARY. 2009.' [their grammar and punctuation]
As a result of this 'mix up' it appears that my numbers came up in the '3rd category' and I have won 715,410.00 euros.
There is a comprehensive form for me to fill in with my name, address, phone number, bank details, and next of kin's name, address, phone number, etc.

And what a coincidence! Several months ago I had an 'award claim final notification' letter from the 'El-Gordo Lotteria Primitiva' saying that I had won the lottery in the 3rd category, and if I provided all those personal details I would receive 615,810.00 euros.

So my advice to you is to ignore the letter, and in a few months time you will win an even bigger prize ...
