Palm Beach Jewelry G Defective gold chain Boca Raton Florida

I ordered a gold chain from Palm Beach Jewelry paying $499 on .june 5, 2018, and the chain broke I sent two emails and received no response so I called them and the representative is telling me that there is nothing they can do, I asked to speak to a supervisor and was told that the supervisor was not available. The representative asked me how come I didn’t get the extended warranty and I told her that I was not aware of the extended warranty so she said there is nothing they can do. Do not do business with this company they are a ripoff.
