I'll side with their research and mathematical modeling and not pay them and just pay for repairs/replacements myself. 

It's simply mathematically impossible that he wasn't complicit in this scam.Also, ask yourself this question.. if there are so many happy Morris Invest customers out there as he claims, why don't we see them on BP?
