On June 2013, recieved a promotion letter on how to make 976% on your money in less than 97 days and without any work at all 100% Guaranteed by David Smith and his company.its a program call summer cash and gas certificates.This are promoted to major businesses all over the country from June- 21-thru Sept- 21- 2013. How it works, you invest on mailing spots that cost 500.00 each At the end of sept 21 2013 it was to end and you would receive 976% profit of 5,070.00 per mailing spot 100% guarantee and even with a selected protection gurantee of your choice. Well not true, waited till sept 30 2013 and no respond from nor thru 1800#. No one to answer phone# and no contacts. I invested 5 mailing spots and by Oct. 10 2013-recieved thru mail some worthless gift card vouchers that xpire one year after activation. They are only certain discounts that you can use. According to David Smith that his company did not do so well and could only return this worthless vouchers equal to the amount you participated. He did not promise his 100% guranteed money back per letter stated. People beware of his next scam that is due on December-1- 2013-thru March-1-2013. I have stated that i wanted costco or walmart credit card only per agreement if could not come up with any monies, and instead recieved some worthless vouchers that it would take me several years to use. He is a scam person out to get greedy and ripp off people just like i did and fell for it. I have talked to my attorney and will fill a complaint and possable indictment for fraud with the us district attorney and the us postal inspection service with they contacted me already. I am requesting my full refund and hoping David Smith does.
