They don’t care about social media. I’ve walked. Only once did they actually let me leave and that deal was so lopsided that I’m glad they did. Granted you didn’t get exactly what was agreed but 5% below invoice seems more than fair if the competition wouldn’t go there. Assuming no dealer fee or bogus charges.I had the deal worked out.... In writing but they said take it or walk. It was 5% under invoice, I waited forever and didn't want to lose it. No dealers around would match it so I took one in the can and just agreed. They will pay on social media.
Me personally. I would have walked on principal. Paid more elsewhere. I stand by my word. Expect the same in return. Why I always get up soon as they try any tricks.
