Highly Disappointed in product quality

My wedding ring was purchased in May 2023 and was kept in the original packaging and not touched until my wedding day in September. I was only able to wear my ring for less than two months before the gold plating of the ring fell off. I took it back and had it booked in for assessment. I called in 1 week later and was told that the ring had been returned. When I went by the store I was told that it had not been returned and I will have to pay an additional fee to have it fixed (which is almost half the price of the ring) as they didn’t find fault on their end or I can have it returned in the same condition, as it was 4 days passed the guarantee date. I take pride in my ring and took impeccable care of It. I am highly disappointed as one would think the quality of the ring would last much longer than 2 months.
