DH and I have moved into a housing association property (ground floor flat) with our 10 week old DD and dog.
Our next door neighbour approached me in the local shop and said 'I hear you've met (let's call her) Sally'. I didn't have a clue what she meant and she proceeded to tell me that Sally (the person in the flat directly above us) had told her she had shouted at me in the street! I was baffled by this as no one has done anything if the sort and I don't know Sally at all!
Since then I have received messages on Facebook messenger from Sally on a few occasions that have been 'nicey nicey' about her not wanting to be a nuisance but can we please stop slamming doors/talking loudly/banging cupboards. The walls are thin and I apologised on each occasion for disturbing her, even though I know we don't make that much noise and have previously lived in properties with thin walls with no issues.
We made a huge effort not to make a noise as I was getting quite anxious about it and after 8pm pretty much tiptoed around the flat, I couldn't relax. We're not noisy people (we'd be waking DD if we made the amount of noise she's claiming to be disturbed by!)
Tonight I broke a glass by accident and the dog nearly trod on it, DH luckily saw and said 'no' loudly before he hurt himself. Next thing we know there's a massive banging on the ceiling, so loud it woke DD and started the dog off barking which he very rarely does! Sally then messages me saying she's reported us to the HA for the noise as it's 'beyond a joke' and that we 'obviously don't care' despite all of my previous messages apologising/trying to be nice.
Spoke to the previous tenants who said they had the same problem (they had 2 small children) and said she banged nearly every night at then.
Should I report her to the HA? Do something else? DH made me take screenshots of all the messages and block her. I just can't relax at home and am worried especially by what the other neighbour said, as Sally is obviously the kind of person who goes around shouting st others (I hate confrontation!)
