True!Seems the OP has placed too many burdens on himself to adequately resolve the issue.
Doesn’t want to inconvenience the workplace
Doesn’t want to smear the dealers reputations or their sales
Wants adequate resolution to his issue which appears to be less of a priority than the aforementioned points.
In other words, you’re being entirely way too diplomatic. The “I’d like to have this fixed but only if there’s no hard feelings all around” approach doesn’t usually end in your favor.
