I had a terrible experience buying something on Etsy that was not as described. When I asked the seller for a refund, she agreed, then changed her mind and stopped responding to me.
I disputed through PayPal and then received a series of harassing e-mails from this seller demanding I send back her defective items immediately or she would take "legal action." Keep in mind the items were less than $10 and, accounting for the damage, probably worth less than half that amount. Etsy refused to block this seller for misrepresenting her merchandise or block her from contacting me. It wasn't until I put a complaint into the BBB that I got any response from them, which was only to tell me to stop contacting her?!
Complete BS and total waste of my time to have to deal with this mess. Most of the sellers on Etsy are nice, but you will rue the day when you have a crazy one and have nowhere to turn for support!
