A few things: Your mistake was constantly going to the manager thinking you would get what you want by doing so. In reality, this is a strike against you. The manager has identified you as a problematic client who is going to complain non stop if things don't go your way. I can only imagine how the conversation went - "I spend $45,000 gimme my bag!"
You keep mentioning 'how much i've spent', 'i've spent this much.' Honestly, $45,000 after 15+ months AND 2 non QB isn't high in the Hermes world. It's quite typical spend, actually. Especially in NYC, where people can and will spend 6 figures on a whim but not expect anything in return. I think you need to adjust your expectations. It sounds like you've succeeded in obtaining QB's (with less spend) from a country where they're more upfront regarding the path towards a QB. Perhaps you should maintain that previous relationship instead.
You mentioned "My wishlist is broad, so they could have found me a bag if they wanted to." That's absolutely true. If you didn't constantly make shopping contingent on a bag offer, or go to the manager complaining about everything, you probably would have your bag by now. Hermes absolutely does reward (lower spend) clients who are nice, drama free and not demanding of QB's.
Clients are never in the drivers seat at Hermes. You are never guaranteed or promised anything from H, except the items you paid for and physically carry out of the store. I've said in previous posts that you never want to be that client that is obviously angling for a QB, because SA's pick up on the desperation/eagerness and sell (as that is their profession). On the flip side, no one held a gun to you saying you have to buy X Y Z today. What you spent and what you got for your money is all on you.
My take: You need to take a break from your store, but I think your home store is done with you. IF you get an offer, it'll be a 'lets offer this person a bag so they don't ever bug us again.'
Edit: and unless you temper/recalibrate your expectations re Hermes in North America, no matter what store you shop at, you'll run into the same issues over and over.
