Good luck. =)
Indeed support is the place to go. But to speculate on the possible outcome, the answer is in general that they don’t have the means to replace items on the live servers and therefor are unable to help you.
However. This doesnt mean that this is a good thing. I am even doubting the need for these rings to be unique. afaik it serves no real purpose then lore (there can’t be two Khilbron’s rings). Though I find correctness in lore important, it shouldnt be gamebreaking. Many people aremaking these mistakes. You can get two rings wich are identical in stats (e.g. Khilbron’s Phylactery and Ouroboros Loop wich only differ in the kind of infusions being possible). The difference in infusions is imo so minor there is no need at all for these rings to be unique.
Arise, opressed of Tyria!
