5 months ago we had some work done on our house which created dust. We told our NDN that we would pay to have their back windows and conservatory cleaned- asked them to book someone at their convenience and we'd pay.
They didn't do anything and after reminding them twice and volunteering our window cleaner we forgot about it.
They then started doing lots of work on their house which has created huge amounts of mess and dust- lots more than our work did, and which has left all their windows filthy. Our garden and windows are also now mucky with detritus from their work, but we didn't bother saying anything as we're about to start work on the garden and there didn't seem to be any point.
Anyway, they have just posted an invoice for £65 through our door for getting their windows cleaned! To add insult to injury the invoice indicates that it was more expensive due to the terrible state of the windows, caused by THEIR building work.
I'm fairly certain no one will tell me IABU to call them rude, BUT AIBU to still pay? I know it's wrong, but I don't want neighbour issues and CBA to start a row over £65. My mum (who is much much feistier than DH and me) is outraged with us (the word pushovers was used!) but we did tell them we'd pay and set no timescale or conditions....
