Low quality and Faulty rings

The most horrible experience ever bought a ring at American Swiss in blue route mall in August because I was told that they could not resize the one I had because I lost the slip. So we decided to buy another ring sumthng smaller and cheaper then the one I already had 3 months now and the cubic stones on both sides of the ring fell out took it back in store and asked if it could be replaced was told that I would have to pay about 2300 mind you this is double what the ring cost on top of that the staff couldn't even assist me but what I want to know is isn't there a police of these kind of things in store I was told its my fault the cubics fell out apparently according to them its wear and tear but I have only had the ring for about 3 months I personally feel that American Swiss is selling the customers faulty jewelry and the fact thatg they don't know their own policy is beyond me. I'm disappointed in the bad service that I received no assistance or even an attempt to help me I was just disregarded and I'm not the only customer that this has happened to I would hight appreciate it if the area manager could get back to me on this matter because I will be taking it further if this doesn't get sorted out. The most horrible experience ever. I have also noticed that I'm not the first customer to complain about your stones falling out trust me I won't be leaving this matter like this.
