Review Agents disinterest

i signed a lease agreement on 01st March, had my bin stolen end April. been requesting Rawson Properties in Ottery to provide bin and to date still no bin. the agent takes a week to respond to my request, if at all. I've been sending emails and whatsapp messages and they ignore it. I had a issue with maintenance as well, window handles breaking, washbasin cracks etc. took them 3 months to have that sorted. i was told carpets would be cleaned before i moved in, to date nothing. the service has been disgusting!!!
