Samsung s23 ultra and 6 watch bundle 2023

I had traded in my old phone for the Samsung s23 ultra back in December. There was a promotion deal where if I had traded in I'd be able to get $1000 off and free Samsung 6 watch. When I had went in before 14 days for the watch I was told I had to pay $10 for the line which was fine. However now I'm in the 3rd billing cycle and my phone has the promotion but my watch doesn't. When I had bought the phone and watch it was at retail stores. When I had bought the watch they couldn't find the promo but after looking saw it said I'd be all good and everything should work out. I had to ship in my phone for trade in but wasn't informed of what the promo code I should have put in. I had contacted the message help system where I was told it was tradeOffer23. 

Now that it's mid March I had went to a corporate store for help and saw on the bill that my phone had been put on the promotion deal but my watch wasn't . I had shown my screenshot and was told I should call for help. So I did, but I was told it doesn't exist. I had asked if there was anything they could do to help me since I was under the impression that the watch would be included. I was told I couldn't refund or return unless I were to pay off the watch in full. I was also recommended to go back to the retail store and ask them for help. I doubt that going will help with anything since they probably get rid of there promotion information as well. I feel stuck and don't know what to do since I could've just waited for the deal with the s24. How can this be made righ
