My Yodel parcel says delivered but I have not received it. What should I do?

First check any safe place, porch, or with a neighbour, since Yodel may leave a parcel in a safe location and record a photo as proof of delivery. Look at the tracking page for the delivery photo or location note. If you still cannot find it, contact the retailer who sent it, as the sender holds the contract with Yodel and can open an investigation.
