Disgusting treatment by American Swiss

My girlfriend bought a Police bracelet at American Swiss Hemingway's East London. Way before the warranty wore off the bracelet broke and we took it back in Feb 2019. We were told it will be repaired and returned by the 6th of March 2019 but this day came and passed without ANY communication from them. Eventually we went and inquired and they said they would get back to us and again there was no communication until we went back AGAIN to see what was going on. This was now at the end of March. They said it was showing on the system as "on the way" and we should wait as they will let is know as soon as it arrives. Once again there was nothing from them in terms of communication until we went to find out once again what was happening. They now said the bracelet was sitting at their repair agent still not repaired as they were unable to repair it. On the second week of April I got a call and they told me to come choose a replacement bracelet since they could not fix my one. I was told I would get it the latest by Monday 15 April 2019. Come Monday I'm getting more stories about the the damn thing not having been shipped when it was meant to be shipped and now I must wait for it to be shipped overnight and I will get it the next day which is today 16 April 2019. I get there today and what's being given to me is TOTALLY DIFFERENT from what I was shown which is what I chose. The in-store staff themselves agree and can clearly see the difference. They call the store manager Chantelle who is apparently on lunch and she simply tells them I will need to find the receipt or wait for them to find it in records so they can try and see if any other store had the same one I had rather. Now it's almost a nine months since the original purchase and almost three months waiting for them to repair it. How much longer will o have to wait for them to find another in another store!!!??? And what are the chances of any other store having that exact same item after so long!!!??? I feel I'm being seen as an idiot and that is one thing I do not appreciate. I will be escalating this matter as high as I possibly can. I've been so patient for so long and they can attest to it in store. I've maintained and kept calm through all the up and down and this is what I get in the end. This is utterly disgusting and annoying.
