well, I am sure something can be worked out. Name calling doesn't help.
I suggest you guys to calm down and solve it in a professional way.
For richard, I think you should email King and ask for compensation. It was clearly advertised as 14K. So you should get what you paid for. Does 4K make a big difference? I don't know. But I think it's your responsibility to make King to get it fixed. Maybe she can get you a replacement or something.
For watcha, maybe you should accept a partial refund. Honestly, Richard shouldn't be blamed for the mistake.
I checked the price on ebay. The price difference between a 10K and a 14K isn't that much. If I were watcha, I ll probably just take the bracelet and accept a partial refund from King/Richard.
