Drmac,
So glad that you contacted the right people at Marquis. I have had such a positive experience with Marquis that I couldn't imagine the problems that you experienced.
Sometimes it is just a matter of getting to the right people and presenting your case to allow them to make things right.
I also imagine that some dealers are not financially able to provide the level of service that they did a couple of years ago. It sounds like that was a big part of your problem.
Perhaps this will also end up being a learning experience for the tech who serviced your spa.
Let us know how it all works out.
Boni
