Last week I noticed the tenant in the next door flat has been running an extension plug from her flat to a plug in the communal hallway (which I have to pay for via service charge). When confronted about it she apologised and said she would remove. Today I saw it coming back again, this time just discreetly hidden under the carpet!
I had a go at her about it, which she said is due to her plug not working and the managing agent said it was free (although not sure how much I can believe this story now 🙄).
Have anyone run into a similar situation? I'm hesitant to report this to the management company because I'll have to disclose it when selling, although I may do it if I ever see this plug the third time!
