First of all, I am happy to be told I'm being a cowbag. :)
A bit of relevant background
We moved into this house in September 2024. We purchased the house from a single woman named *Jane (widowed) in probably her late 50s/early 60s.
About a month after moving in, we received a "final demand" in the post for a small amount she owed to O2.
She hadn't left a forwarding address, so I enquired with the estate agent who handled the sale, and Jane begrudgingly gave them "permission" to give me her new address (a house on the other side of our large town). I dutifully re-posted it and thought no more of it.
Then in about December we received another "final demand", still for O2 and the same amount. I put this one in the post to her as well.
I've also sent on Christmas cards, and various mailings from different animal charities.
Fast forward to about September this year, we received a credit card from a reputable bank in the post, for her. We kept hold of it for a couple of weeks, expecting her to get in touch when she realised her error (after all, she knows where we live!) But she never did.
At this point, I was getting fed up of being her forwarding service, cut the card in half, and posted it BACK to her bank, with a covering letter.
Fast forward again to this week. We received ANOTHER credit card for her (same bank)! We roll our eyes and put it to one side - how on earth has she not changed her address on her BANK?!
Then today we received a "PIN reminder". Her ACTUAL PIN NUMBER.
In all honesty, I feel disinclined to put her new address on it... I've done it enough times now.
Would I but a total cowbag if I just returned it "Not known at this address"? Solely because I think she's stupid?
