I sold some items back in April, one item was returned by the postie yesterday after it was unclaimed by the buyer and sat for at least 3 weeks in the Royal Mail depot. I had to chase this buyer for payment but I haven't heard anything about the parcel not arriving. I sent an email yesterday asking what they wanted to do but no reply as yet. I am not really sure how best to proceed now. I could just refund, if so do I take off the postage charge? What if they say they want it still, can I ask for a second postage payment?
