SW Engines Remanns fraudulent, poor customer service, poor quality parts Tulsa, OK Nationwide

I purchase a used engine and a three-year parts and labor warrany for my Mazda Miata on October 1, 2016 for $2395.  The enigine was shipped in a timely manner but once it was installed we discovered that the engine was damaged and sold to us in poor working condition.  It made a loud and constant knocking sound. 

I contacted this company to begin the warranty process and was asked to provide an installation and diagnostic report.  At this time I also requested a diagnostic and documentations about the engine that was sold to me.  Accoring to the warranty representative I spoke to, they do not have this documentation.  According to him, they run the engine for 30-60 minutes to test for oil pressure and knocking and then store them for an uncertain amount of time.  

My mechanic provided the company and myself with multiple documents stating that the engine was damaged and was not suitable for driving.  Even with this information received, the company refuses to uphold they warranty stating that we didn't send the correct information. 

Every interaction we have had with the warranty service reporesntative, Alex Black, has been extremely rude and hostile.  We requested the contact information for his superiors on several occasions and we have yet to receive this information.
