I took 2 parcels to the Post Office as a drop off for Evri for two different buyers. One buyer is saying she received nothing and the other buyer the wrong item. I have looked at my receipt and found that both items were accepted under the same address AND barcode number...??? I really don't know where to go to sort this out. Obviously I have asked the buyer who received the incorrect item to return is and she has but I guess I cannot claim for the lost one? I would appreciate any help/advice
