I'm in a bit of a predicament. My partner ordered a £75 item from a private seller a week or so before going into hospital which she thought was going to be one or two nights - it now looks like it could be two weeks and she is barely able to hold a conversation with me let alone chase anything up.

She mentioned it to me and I checked her eBay account on her iPad and it said that it had been delivered by Evri on 7th May but there is no sign of it. I tried to obtain proof of delivery by entering our postcode on their website but it said that the postcode was incorrect. I checked that the postcode on the order details was right and it was the same - so despite it saying it was delivered to supposedly the correct postcode, I can't see proof of delivery.

Yesterday whilst visiting her in hospital, I sent a message to the seller via her account, informing them who I was and the situation but when I visited today and checked her messages, there was nothing from the seller but a response saying that because the item had been sent via Simple Delivery, it had to be dealt with by eBay customer services.

I actually had an Evri delivery today and the driver knows the area well. I had hoped that he might be able to trace the proof of delivery without having to enter the postcode but he said that he couldn't.

What can I do if my partner is too unwell to deal with this?
