I used to live on Lordship Lane and always either got no post or both our neighbours post, and I definitely had post go missing. Unfortunately I don't know if neighbours kept or it was never delivered. I did report this over the phone but RM were not very helpful and actually said the post was delivered to one post box as the postman had advised there was only one post box for all three properties. I offered to sent a picture of all 3 letter boxes, but the lady declined. Have since moved so I'm not sure if the problem was solved but it was incredibly annoying.
