Galaxy Watch 5

I did the exact same thing. I went in a TMobile store and purchased the watch. I specially told the sales person that I wanted the watch that was on sale. I purchased the watch thinking that it was going to be $100 or so but it turns out I had to pay full price for it. During the time, I was still part of Sprint's network and didn't fully merge with TMobile until April 2023. The watch was purchased in September 2022. I was not informed that I was still on Sprint's network until recently. Unfortunately when this whole merger happened, I feel like we got the short end of the stick with things since we were not given the full information that was needed during the time it was needed.

I usually keep a copy of my contracts in an email just in case they are needed for some reason. In this case, my contract wasn't needed but finding the discount code was needed since every person that I spoken with was not able to provide me with any information. Everyone told me that they couldn't see any previous discounts. After months of searching for everything, they basically told me that there wasn't anything that they could do since I waited so late. Basically making me feel like I should've checked after them to make sure that they weren't getting away with anything. Maybe if I would've went to them sooner then I might have gotten better results but I doubt it. I really hope you have better luck than I did.
