Hi I have sold an item via eBay. The buyer has requested a refund as the item has not been received. I have the tracking number and it suggests they have tried to deliver on 3 occasions but buyer not in. It was only sent on Friday. I have requested a redelivery for her today but it hasn't happened and she wants the refund sending. Should I just refund and cut my losses. Had a bad feeling about this from the start as she took ages to pay.
