apartmenr not maintained

I moved in to one of the apartments managed by Trafalgar only to find the shower blocked and the bathroom roof molding. It is a necessity for the owner/agent to maintain the apartment for a new tenant and to check for possible repairs before letting it again to a new tenant,clearly this was not the case with Trafalgar. After I emailed and phoned the agency numerous times there was no action taken until I had to throw a tantrum at the maintenance guy who sent contractors after I had fixed the shower from my own pocket as I had to shower at the gym or ask neighbors whilst my rent was paid up!! My bathroom is disgusting and I am tired of running after this company all because of their incompetence
