In the U.S., the law is that pressurized gas tanks need to be inspected by licensed test facilities, and only they have the authority to condemn a tank. Dive shops have no such authority! It doesn't matter one iota if they have taken any private courses (like PSI) on scuba tank inspection, those are basically meaningless in terms of the law allowing them to disable or disfigure customers' tanks. What they can do is refuse to fill them or put their sticker on the tank. That's it. In fact, they can refuse to fill any tank, for any reason. They own the compressor. But they do not own your tank.
Find another shop and hope that the next one isn't even worse, hehe.
