Proposal gone wrong!

My fiancé proposed NY2021. The look on his face was priceless for 3 reasons. 1. He dropped the ring. 2. I said Yes! 3. The ring didn't fit. He was taken back when it didnt fit but I was so happy he didn't have a chance to be anything else but happy with me. I did laugh about it that night. It wasn't funny anymore, once we had a talk the next day when he shares with me his experience with *Zales* I felt bad for my fiancé. He had a firework show, our parents were their to witness this moment and he planned all on his own. This was his moment just as much as it was for me. He said the lady who helped him kept advising him not to resize till i went in and tried it on. He said no i definitely know her size, she can't know I'm proposing please resize it. He was asked to pick up 2 weeks later as he did. Note: We've been dating for 4 years he's bought me a ring or 2 before so knowing my size is something he has on point. So the same day when he shares with me what happen. We take it back to *Zales* to have it resized. Mind you we think its my ring size which he sized as 9.5. I'm still joking thinking wow my had gained quarantine weight too. But no the proof was there the moment the manager checked the size. The impatient jeweler who helped my love mistake was caught, the ring size was a 7. Huge difference so you could imagine the look on his face and mine. It was never resized like he asked never touched why did he even wait those 2 weeks! It was still the original size. We spoke to management that day like I mentioned he tried to give us a 20% discount on my fiance ring i was thinking of getting it for him but we said no we will wait. Did a search on *Zales* come to find out there was a actual discount promotion already on site for 20% off. So that discount had nothing to do with *Zales* employees and manager feeling sorry for there mistake. We're waiting to see what can be done manager above him is suppose to be contacting us soon. But what will be done? That was not cleared up, can't change our special moment and our disappointment. What do I do about them taking my loves money so quickly?! Rushing him out the door and taking his special moment not seriously when this is something they specialize on. All I know is 20% meant nothing , they are in the process of resizing my ring (it is insured) and management has placed a request to get my ring returned back to me the right size! sooner than 2 weeks.
