I sold something that was low value and within a week of the auction ending the buyer was messaging it had not arrived. It was sent RM 2nd class, so they were only allowing 3 days for delivery. They have now said- a few days later- it's still not come.
I am not sure this is the case but clearly it's my word against theirs. They only have a handful of positive feedbacks in their history.
I know in theory they should wait 3 weeks before I can raise an enquiry via RM but I really don't want any negative feedback.
