The old tenants moved out 6 weeks ago. I moved in 3 weeks ago.
They didn't leave a forwarding address in the flat or with the rental agency so I have been returning all their mail to sender (I printed out a whole wodge of stickers that basically say 'not known at this address - return to sender')
One of them has just come round to ask for their post. I explained that I have been returning it to the sender. They were pretty upset as apparently some organisations have been getting upset (banks/ credit card companies) about the stuff being returned.
I then explained that they could have set up a royal mail forwarding service (I've did it, it costs 40quid for a year and there was only a very brief set up time required) or left me or the agency their address and stuff would have been forwarded. I have said that I will forward any mail which arrives from now onwards (and she has left their new address which I will print on stickers).
AIBU to think this really wasn't my problem and as an early thirties professional (like myself) she really should have sorted it out and not got cross with me.
They also didn't cancel their utilities accounts / inform the council which has resulted in me having problems opening up accounts/ getting a parking permit which was hassle I didn't need.
