Should I ditch the AD?

[Hawk]

I've been working with my only AD for approximately 4 years with the same sales associate. Spend ~$160k across diamonds, ladies DJ, PM Daytona, and gold jewelry. Recently he missed two semi-important milestone opportunities with a "we haven't received any watches" with ample notice (2-4 months). In the past year the rep has also gaslit me on three occasions:

1. PM Daytonas are more hard to obtain than SS Panda (which I specified I wanted)
2. OPs are the scarcest Rolex models in the store
3. They don't carry extra watches "in the back" (this is the largest AD in a major US metro)

I have made clear that I'm not buying anymore diamonds for the wife or watches that aren't on my specific short list. I live 3 hours away so not in a position to drop in more than once per quarter. Does it make sense to just go grey at this point based on this context?
