They take out the middle residents and top resident’s bins out every week (not ours or our neighbour across the landing as they would need a key for access) and complain how no-one else does it.
So, they don’t take your bin out because they can’t access your bin? Why would that indicate that she has an issue with you?
they stand at our door shouting ‘oh it’s me taking the bins out again’ - no one asks for them to do this.
This clearly isn’t aimed at you because they don’t take your bin out and can’t access your bin.
they always look in our baby’s bedroom window (where they keep their bin outside our baby’s window)
They’re probably looking at their own reflection in the glass tbh.
they have sent us (only us) a bin collection dates calendar and now recently they take the bins onto the road (not pavement) so takes up a parking space on the street.
So? They take everyone else’s bins so no need to give them the schedule. Maybe they wanted to ensure you don’t miss a day (they ensure no one else does by taking their bins). If people miss a week in a communal building then it stinks for everyone.
they have contacted me saying that ‘our side’ of the back shared garden needs a gardener or to borrow our lawnmower although my title deeds state that it’s a shared back garden therefore all 6 residents would need to seek this, not just individuals on one side of the building.
So, you are neglecting your obligation to jointly maintain the back garden? You previously said that all the gardens were private and yours is at the front so this doesn’t add up. If you mean the clothes drying part, you still have to contribute to maintaining it whether you choose to use it or not.
We do not let anyone use our lawnmower as our previous neighbour damaged our 3 previous ones and we have to buy new ones each time - we just lawnmower our own private garden.
How is this relevant to your point?
when they receive a voicemail they constantly ask me to go up and listen to it (despite having major surgery c section) and don’t ask anyone else in the building.
What’s the context for this?
Sounds more like you have a problem with her than that she has a problem with you.
