My buyer opened a case - item not as described - and I agreed a refund 17 days ago. I assumed she'd decided not to bother (it's a dress for £10) but today she emails me to say that she will try to do it tomorrow. Do I still have to accept? I don't like the idea that she's worn it in the meantime. Her reason for saying that it was not as described was because she said it looked like it had been worn more than three times (it hasn't).
