If they didn't give you a credit that promised you should follow up and hold them accountable. They should have logs of account actions, and if not, you should save a log of the chat where it was promised.
Further to this, my £10 credit for missed deliveries could only be applied to items sold by and shipped from Amazon. No third party sellers. It also only showed up right at the end of the checkout process just before the final click.
Mentioning because I both thought I hadn’t been credited with it (first time of chasing Amazon I actually hadn’t it turned out...) and then was miffed I could only use it on a subset of items.
