Cold calls from the dealership itself is a surprise! I wonder if they're going to go back to 90's sales tactics are bring their cars door to door asking you to test drive it on the spot. haha
i wouldn't pick on or hassle the employee making the calls. They're just doing their job to put food on their table. Pretty sure those are minimum wage jobs too.
Sure, it's annoying as heck, and I want to annoy them back, but if you take a step in their shoes, they don't want to call you either, they're paid to by the higher ups.
I just say i'm not interested and if they keep pressuring I hang up.
