科索沃采购需求：COLMI R10 智能戒指，推荐，购买者，购买，评测

I'm reaching out due to serious concerns with a product I purchased, which has malfunctioned shortly after use. The lack of response from customer support has been incredibly frustrating, and I'm also disappointed to learn that warranty claims are not being honored for customers in Kosovo. I need a clear explanation of this situation, along with warranty support or a replacement for the faulty product. If I don't hear back soon, I'll have no choice but to escalate this issue to consumer protection authorities. It's crucial that this matter is addressed.
