Hey,
So I'll explain what happened.
Buyer emails asking about tracking because an item sent on the 15th hasn't arrived yet and that she needs it for this Friday (today is the 26th). I explain that i don't provide tracking automatically (optional upgrade at checkout) and that it's probably stuck in customs. She asks why would it be stuck in customs so I told her the item is coming from the UK. She says she didn't know that (even though it says so on my page) and then messages me again demanding a refund because clearly the parcel is lost. I told her that it's been less than 2 weeks which isn't enough time for the parcel to arrive and that it wasn't my fault if she wasn't aware the parcel was coming from the UK.
She messages me back saying if it hasn't arrived in time for Friday she's going to file a claim and get her money back. I told her I would happily offer a refund once she returns it to me. She refuses saying it's unfair, that I don't provide tracking and that it's fault the item hasn't arrived.
I suspect she will file a claim and get her money back even if the item arrives after her event.
