I paid £450 for a domain on 20th February using paypal and never received the transfer documents. I requested a paypal chargeback but got no where. Here is the paypal response. "Thank you for registering your complaint about this transaction. Unfortunately, this type of transaction is not eligible for PayPal dispute resolution. We encourage you to continue to work directly with your seller, as we have found that many misunderstandings reach amicable solutions through communication. " The seller is an Acorn member who has not responded to emails or PM's. What is my best course of action?
