american swiss is just not what it used to be

After taking back my engagement ring for the third time - reason being - diamonds falling out, ( taking it off when sleeping and bathing etc. Which shouldn't be neccecary) I am very disappointed in the quality of American Swiss. On their leaflets stating \All our diamonds are conflict free..."The staff working at the Heidelberg mall American Swiss is also not very helpful asif they want to imply this incidents happening is my fault. Materials used are not as good as they state. My white gold ice diamond engagement ring has spent more time in their shop in for warranty fixes then on my finger."""
