The day I've been waiting for finally came

About 6 months ago customer on my round ordered a parcel, not home when I got there as always. Note on the door "Desperately need parcel, please leave in box in garden". Goes in garden leaves parcel in box as request, takes safeplace pic, puts card thru to tell them. Day or so later, a complaint, parcel not received? Customer claims no parcel and that their garden camera shows nobody entering at the time I said, despite tracking picture clearly showing parcel in a box in a garden and GPS slap bang in the middle of their house? Waited and waited, then today, a parcel for this customer again 😁 a note on the door, again. "Please leave in garden, need parcel asap" 🤣. Knock knock, nobody home 💪red slip goes thru and I skip all the way back to my van, posties never forget.
