I received a delivery receipt yesterday,receipt number ********,your courier ticked all three boxes saying *st attempt *nd attempt and final attempt,I was at home all day and my door buzzer did not buzz at all yesterday as I live in a block of flats with an intercom system. I was not expecting this parcel until the **st but your courier has ticked the box that my parcel was left in my porch which is impossible as I don’t have a porch as I stated I live in a block of flats and there are no porches on any of our flats so I don’t know where your courier left my parcel and I have no clue as to where my parcel is now I have sent an email to the company that I purchased my package from with the same details and am awaiting a response as to where your courier left my parcel I can only assume it was left outside my door which is publicly accessible as I am the first flat on the ground floor anyone could have picked up my parcel and I am now without my parcel and the money I paid for it unless your courier left my parcel in a different place because they certainly didn’t leave it in my porch that I do not have!!!
