As heading states buyer says not arrived but picture of outside his hall ,its a flat, and marked as delivered ,its never happened before and i sent 3,000 items all over the world but heres the thing,what are the chances of this happening to a buyer with no feedback its zero, now he says can i post to another address so he recieves it,if thats ok not sure if it is,when questioned who lived their he said he had other properties as well ,also then said it might have gone in the empty flat opposite as they died last year and still empty ,i know its only £20 but annoying as i can see a negative coming as well if i dont send another ..advice anybody.
