Absolutely useless

I am a tenant in a property they manage. Absolutely useless bunch. Struggle day after day to try get any responses. Sometimes a week will go by with no reply on requests. They do not notify you if your lease is up for expiry AS PER THEIR OWN LEASE CONTRACT which says they must notify you within 40-80 business days. They do not answer you on queries regarding their monthly invoice. Absolutely shocking.
