“asking what day will this happen and can I see reciepts.” The Lot Owner above has no moral or legal obligation to allow you access, notify you when works will be undertaken, or show you receipts. I don’t know why you think this is reasonable. I would consider this request quite rude and aggressive. It is exactly because of your actions to date that they are now ignoring you.
Additionally your OP is not clear what the noise issue is. Is it that they ‘slam’ cupboard doors? or front door? Maybe pump the hate breaks and instead if insisting “something be done” ASAP and threatening legal recourse; go and have a polite chat with you neighbours. Tell them its disturbing you and you would be terribly appreciative if they could not slam the doors; and hand them a $5 packet of rubber or foam door pads from Bunnings. 99% of people, if an issue is made known to them (cause I can guarantee they dont know its annoying you), asked nicely, will do the right thing.
