Just two questions here and it is this. Do you have a signed written contract with this complainant for the $2K he paid you for your service specifying what the $2K was sent to you for and do you have anything in writing in said contract saying he is not due a refund of his $2K under certain circunmstances, or is this all just talk on his and your parts? If it's all talk, then I'd suggest you start putting out written paperwork to CYA or you'll continue to have people that you say are lying that appear to have a legitimate complaint. All we know is that the guy says he's out $2K and you have admitted you have his money. PS: My 30 year career was in consumer protection with the state of MI, so I know just a little more than the average guy as to what should be done when goods and services are bought and sold!
