1.Please make sure this buyer sends it back to you recorded delivery or she could say she has sent it and then keep it. Buyer to pay postage (recorded and extra insured if worth over £46) for changing her mind because your item WAS as described.
2.Check all the buyers detailed feedback to see if there is anything suspicious.
- Contact ebay customer support and keep the transcript of the written conversation you have with the customer support assistant so you have evidence of their advice.
- Tell your buyer the transaction will be monitored by ebay and all feedback too.
This week I had a message from a buyer saying a dress didn't fit and could she return it. She had had the dress for over 2 weeks. I contacted ebay customer support via instant chat and expressed my concerns while also pointing out her very poor feedback. Ebay said they would support me and remove any neg feedback should she leave it. I messaged the buyer and said ebay would be monitoring the transaction and that she could return IF the item was in EXACTLY the same condition and wrapped as carefully as she had received it and she would be responsible for return postage. I told her ebay would be monitoring her feedback and I have not heard a word from buyer since.
I have changed my returns policy to say contact about returns to be made within 7 days.
You have done everything you should do and if you are 100% certain your bag is authentic then make that clear to buyer and that if they have changed their mind about the bag they could list it on ebay themselves.
Good luck. Most people on ebay are honest but there are a few that spoil it.
