Poor customer service after purchase

Full Review
I ordered a ring from this site last year, probably 8 months ago.  The customer service was good.  They responded to my questions quickly.  The price was competitive and I don't remember having any problems with shipping.  Customer service after the sale, however, is non-existent.  I need the ring I bought from them resized.  The maker of the ring has free resizing (absent of postage of course).  The only catch is getting the ring from me to the maker through a middle man - the company I bought the ring from, Sea of Diamonds.  After two emails and a phone call two weeks ago, I have not heard from the company.  The person I talked to on the phone told me he would get back to me, but he hasn't.  What is funny is that before I bought the ring, I had inquired about this free resizing and how I would be able to take advantage of this, the customer service rep I talked to said just to contact them and they would take care of it because (with a chuckle), why would a store you didn't buy the ring from help with that.  I guess the store you do buy it from won't help either!
