The drivers are supposed to photograph the parcel, it might show it sticking out of your letterbox. Can you enter the tracking code for proof of delivery.
Yeah, that's how I know it was nicked. They left a picture of it hanging out of the letter box, but when I went down to get it it suddenly wasn't there.
Will the company who you brought from supply a replacement seeing as they choose to use Evri, they can take it up with them and in the meantime get you what you paid for.
