Good afternoon-
Vendors who use "bait and switch" tactics such as this, on unsuspecting customers, do not deserve anyone's business. The sad thing is, consumers must be especially vigilant when purchasing high dollar items and must know how to "force" vendors to honor their agreements.
When making a high dollar purchase, such as this, the only thing that matters is the quote. If the specifics of what one is purchasing are not on the quote, it will be impossible to argue for a correction, afterward. I have two decades of expereince in this area, with regard to firearms purchases (250, or more weapons purchased at a time, on a regular rotation.)
My suggestion is, demand that the vendor put what they are telling/selling you in writing, on the quote, so you get what you ordered, and what you paid for!
Kind regards,
