My mum was clearing some things out and asked me to sell a few pair of shoes for her so I put them on a low auction bid and all 3 pairs were going to be sent 2nd class delivery and it states this on the ad. So 3 items posted the next day after auction ended, 2 buyers received their shoes no problem but the 3rd messages me 2 weeks later to say she never received her shoes so I sent her the proof of postage that had a reference number on them. I also put in the tracking number on RM website and it says they got delivered on the Saturday ( 5 days after I posted ) before noon and the name of the postman that delivered the shoes. The buyer said she was in and she will check with RM. So I suggested for her to check with neighbours and postman. Fast forward she has now opened a case with EBay and I have defended myself saying that I have done everything from my end. I've told her to put in a claim on RM as either parties can submit a claim but I don't see why I should claim as it says parcel has been sent. She should claim so she can make a declaration and then I mentioned that it isn't possible for me to go knocking on her neighbours doors and asking the postman so she said I was patronising her but I am only stating the facts. I mean how am I really meant to know she didn't receive them. She paid £26 for the shoes. I have never had any buyers claiming they haven't received items before and always sell in an honest, genuine manner. Has anyone had any experience of this or been in a similar situation? What is eBay going to do?
