Welcome to our forum.
I would consider that great service. Thumbs up for bullfrog
Stuff sometimes happens. One problem, that's barely been looked at, is not a lemon. All manufacturers, of course have quality control. I've never known a manufacturer that doesn't fill each and every spa and test them out at the factory. Keep in mine though, the spas are shipped and trucked around the country. This can on occasion have a negative effect...but you have a warranty for this type of thing It sounds like your dealer is being very responsive and I'll bet they'll take care of it no problem.
