"We have been complaining..."

We have been complaining about loud noises that have been coming from upstairs due to the bad flooring for 2 months now and the living conditions have been hell.The agency clearly doesn't care about our complaints. Our emails are constantly ignored! I mean how professional is that ?... athe guy Peter only replies when it is has to do with rent stuff. His defense is that no one ever complaint before so we shouldn't complaining. Never encountered such arrogance. I don't like naming people but he literally has been totally not bothered about about the situation. Never thought in my life I'd be considering getting sleeping pills from the GP ! Even worse the heating was broken and the electrician was coming to fix it ,we clearly mesioned to him that we were gonna be at home..The electrician opened the door with the keys whilst we were in ! That's just disgusting this agency Is full of bad practices and terrible services atleast from what I can see this guy is not representing the company at all. If things persists we're just gonna get a lawyer to deal with it all. I wouldn't bother renting with them especially around nw area. Get yourself professional agencies.
