Whitehall Jewelers 1

I have bought diamond rings with life time diamond replacement guarantee (as long as I had them inspect it every 6 months). Now the store is out of business and liquidators are selling off inventory and staff were all mostly let go; no one can tell me what I can do to get their jewerly guarantees honored. Junior staff liquidators now hand out "N.E.W." phone number, but after calling them they say that they can not help. NEW says they only help the newest customer who purchased jewerly and paid for the new repair policy. They left long time customers stranded and pissed off.
