I was on vinted for three years and had a 5 star rating, until there was one problem with an item not arriving.
I did exactly what was said to do on the help center to raise an issue. To get blocked, I contacted vinted to get a mundane answer of "I breached the terms and conditions" which ones I have no idea. The seller contacted them and told them I had done nothing wrong and received a refund.
But yet I am still blocked. I have tried contacting them again and again to get the same answer. I also explained that if I did misunderstood anything it was not intentional as I have dyslexia.
But they don't seem to understand.
