Neighbours in society harassing me

Hi ever since I moved into my rented apartment there has been a stream of issues with my neighbours and the chairman and secretary of the building. First they started by telling me that I cant let the moving truck in cos it’s too big then they made me clean the building’s passage because it got dirty due to the workers who were taking the luggage. They had a problem with me having pets in my house - two house cats who never leave my home. The neighbour opposite me has yelled at me, my friends for no apparent reason because she saw my cupboard being moved upstairs and she said I can’t do something like this. The secretary said that the building doesn’t allow pets and that they heard meowing noises. He raised this issue when I went to look for my cat who had gotten out by mistake from my house. Now he’s threatening me saying one more complaint and I’m throwing you out. Is any of this going to work in my favour at all. What can i keep in mind from a legal standpoint
