My husband and I ordered £150 of products from an online shop. We were out when the delivery guy came, and he left the parcel with our neighbour. He posted a note through our letterbox saying he’d left the parcel at number 22. When we enquired with no. 22, they said they’d initially taken the parcel up to their flat, but then they had brought it downstairs again and left it on our doorstep on the street, leaning against our front door. When we got back from work, the parcel wasn’t there, and we could only assume it had been stolen - because it was standing right there on the street for anyone to steal! And the neighbour at 22 admitted that they had left it there. When I suggested to them that they had created conditions in which our parcel got stolen and that they therefore owe us £150, they got very angry, called us unreasonable and are refusing to reimburse us. Am I being unreasonable to think they should pay us back the £150?
