Currently when a buyer tells us they have not received an item, we ask that they confirm their address to check it matches our records.
Then we ask them to allow 7 working day ( not including weekends) and then we refund immediately.
Most buyers are happy but some, understanderbly annoyed that they have not received their item demand an immediate refund saying this is unreasonable.
It is rare and in these cases I stick to my guns but worry about the potential for negative feedback.
