FAulty watch

My Husband bought a watch at American Swiss in 01/06/2018 where the dyle came loose. We send it back to to be fixed but still was faulty. We took this to an independent jeweller and told us this is a manufacturing fault. we took it back to american swiss and they requested a till slip which we didn't have. now they told me they can't do anything without a slip.But i do have the warranty card with the transaction no and date of purchase. I went to the branch 5 times to resolve this issue but still nothing could be resolved. I just want my watch fixed. Stock number: *** transaction number: ca 9098 date of purchase :01/06/2018 store name: ASJ Brits MALL I would like something else in its place or I am bring the watch to branch with a hammer and smash it before all their customers.
