Unfortunately with Etsy you only have 180 days to make a claim so there is literally zero that you can do there. You will also sadly be out of your review window which is the same time scale.
It’s quite sad to see so many people bashing Etsy here.
Etsy is a place full of genuine sellers some of which are the most creative, clever, amazing people I know.
I sell on there myself so I am biased, but the things I sell are very low end in comparison to some of the people I know.
Some jewellers that sell on Etsy have learnt their trade over many years, perfecting it and you will get a ring made with love and a much higher quality than any high street shop. Just because it’s from Etsy doesn’t mean it’s cheap or rubbish.
Whilst yes there are unfortunately some cheap, mass produced items being allowed to be sold on there, it’s important to check the reviews and you can get a good idea of quality rather than relying on photos that can lie.
Please don’t let this put you off buying from Etsy, so many of us sellers love what we do and put so much care into making high quality products and we work hard to give customers a great buying experience. Without Etsy I wouldn’t have the business I have today and wouldn’t be able to put food on the table for my kids.
