No coupon for free faceplate, support unhelpful

I recently purchased and installed a Video Doorbell Pro 2, and it's been working great. On the Amazon listing (where I bought it), the Ring Shop listing, and in the app while setting it up, it mentioned I'd receive a coupon for a free faceplate. Well, a long time later (1 week+) and it's not come through. I contacted support today and had to go through so many hoops, explain that it's a legitimate offer (I was asked to provide proof etc), and finally got to the point where someone agreed to order one for me (they said they couldn't give me a coupon). However they only gave me a limited range of colors, none of which match my house, which is the point of getting a faceplate, right? If I go to Amazon.com or Ring.com I can see the faceplate clearly instock (Mocha Brown). But support refuse to budge and say they can't order it for me. The price is not an issue ($14.99), it's more about the promise of this being free (I remember the old doorbells included multiple faceplates in the box) and then being treated badly during the whole support process. I have no idea what on earth to do.
