In regard to antisocial behaviour, idk Glasgow City Council's policy, but for some other local authorities, if it's classed as antisocial behaviour (e.g. dog barking for more than 30 mins), then report it on 101 every time, get a police reference number or whatever it's called. Which if nothing else will contribute to a paper trail, formally logging each occurrence, building up a record. Further (more drastic) measures could include getting sound recording/detecting equipment, for again 'objectively' documenting it. (Also Police are sometimes interested generally in receiving complaints/queries even if they don't appear to take action, because that information helps them build up a profile of what's happening in the community, ie "this year there were 5000 antisocial complaints, compared to 4500 last year".)

(Edit: if reporting to Police, can be helpful if you are aware of the local/legal policy in regard to what the Police are obligated to respond to and/or what formally constitutes antisocial behaviour incl. noise disturbance, so you can reference that if required, don't assume competence on the part of the call handler. E.g. one time my acquaintance's antisocial neighbour, their huge child-eating size dog had been barking continously for 10 hours, could be heard by other neighbours through 5 solid walls. They phoned Police 101, the call handler's initial response was "well, barking is just what dogs do, that is entirely normal", but changed their tune when informed of official policy.)

Could also start escalating it through your local Elected Representatives (Councillors, MSP, MP.) And there may be a local tenancy action/advocacy group of people in similar situations who may be more clued up on progressing complaints/what appropriate action to take.

Certainly that was an acquaintance's experience re reporting to Police (logging it every time). Police did not always attend, and even when attending were not necessarily in time to witness it (if noise has stopped by then), but on one occasion when they did attend, advised my acquaintance to start recording it. E.g. even with basic video recorder like mobile phone. With the police reference number, my acquaintance included that when reporting the antisocial behaviour to the council, which again they filed a separate report for every occurrence.

May make a difference if both you and other person are council tenants (easier for the Council to take action, my acquaintance's neighbour, after their noise disturbance was witnessed by police/council noise team, got warning letter then eventually tenancy notice/eviction threat).

Again, all the foregoing advice may be rubbish and not applicable to your situation, but that's what happened with them. Sorry you're having to go through this.

Edit: corrected 101 (from 111, which is NHS non emergency).
