Matthew Graves websbestmarketing; Did not deliver on promise of 150% ROI Internet

In February of this year I received an email from Matthew Graves (who operates various online marketing websites and coaching programs via websbestmarketing.com) offering me an opportunity to invest in his Guaranteed Ad Profits program with a guaranteed return on investment of 150%  in 90 days. So on February 27th, 2019 I invested at the $500 level expecting $750 return by June. He instructed me to send the payment via Paypal to another person with the same last name (I assumed it was his wife) which I did. Beginning in June I ended up emailing Matthew over two dozen times in a three week period with no response (I also attempted to contact him and his relative via Facebook messenger but to no avail). Fortunately, since I paid via Paypal I was able to successfully file a claim and get my money back. After my claim was closed Matthew finally emailed me stating that he had been "offline" for twelve days even though I had been emailing him for almost two weeks prior to that with no response whatsoever. He told me that if I canceled the claim then he would pay me the $750 but by then it was too late as Paypal had already processed my refund. (But I wouldn't have been willing to trust him to follow through anyways after my experience.)
