Why would he be entitled to a refund? Galen (Who I don't care for) did his job.
He took the info provided and gave his opinion.
Something with the info convinced him that the car had shady documentation. He was paid to verify the info.... You not agreeing does not mean you get a refund. The service was provided.
No reason to decode the tag or any other info if it, in his opinion, was fake.
Many points of view here.... His (Galen) point being...
Its not right and thats all you need to know... That is a very valid position. If he (Galen) were to tell you what is wrong or what it "Should" be he runs the risk of becoming a resource for bogus car builders.
