A UK seller has sent a faulty item. The seller was unreachable via multiple emails and phones. The case has been escalated to the PayPal. The seller has agreed a full refund (item price+postage), but the I should cover the return delivery cost. This is unfair business, because the item is faulty and any costs should be covered by the seller company. I can't argue with the company directly for the above mentioned reasons (not answering emails and phones), and the PayPal does not offer any more options for the communications. There is no certain way that my return postage fee can be refunded. Any solution for this problem?
