Despite me writing to all my mothers contacts to tell them she no longer lives at home and giving them my address for post, some of them still use the old address. I sent the correct Power Of Attorney to each company, some wanted certified copies, other accepted an email copy, other just wanted certain pages - it took me a long time to do this.
I get frustrated that post if still going to her old house which now has tenants in. I have had to extend the initial one year redirection for another year to give me time to battle with these companies again.
The tenant will contact the property letting company when post arrives although not necessarily immediately so we do get it eventually. I contacted the Post Office to complain that they were not redirecting all letters correctly and was told that if a letter is addressed to the occupier ( as one of them was) they could not redirect it. Also they only redirect letters addressed directly to mum, so unfortunately as my mum had not told one investment company that my father had died, letters were still addressed to him! That one was easy to sort out as I could prove my father had dies thirty years ago!
I have lived in my house for ten years and still get a Christmas Card which has obviously been addressed incorrectly, it’s not for a previous owner nor for any of my close neighbours. All I can do is throw it away as there is no return address.
