Very disappointed with the quality

I am very disappointed with the quality of their rings, my husband and I bought our rings last year early September 2022 at Eastgate Mall and got married on the 23rd September 2022, within 5 or less than 5 months our rings were discoloring, but I thought to myself maybe it's dirty but surprisingly I don't were my ring when bathing, cooking, cleaning, etc, but it keeps on getting brown. I'm just not okay at all after spending so much money for these rings😢 maybe if it was a dressing ring it wouldn't matter that much but my wedding ring, I'm not even comfortable to wearing it... I am planning on taking it back hopefully I'll be assisted and replace it.
