Ring Repair

I took my ring for repair & resize, it had a fallen diamond 2 days after purchase. I took the ring 5 weeks ago, there is no update about when will the ring return. When I account the store, the sale consultant keep telling me that your ring will come next week. They promised to do follow up with the head office, the only answer I get is that “head office line is busy”. The least NWJ could do is give us an estimated time for repair. Mind you, I’m newly engaged to be married & I don’t enjoy my engagement because the ring went for repair & we don’t know how long it will take.
