Bad experience at Sishi's Place Bed and Breakfast aka Ezamasish

I've been booked at Sish's Place Bed and Breakfast in Napierville, Pietermaritzburg for 5 weeks whilst attending a course. Ever since I've booked in I've experienced bad service. The rooms on the outside cannot be locked for the outside and are only lockable from the inside. So during the day anybody has access to your room and belongings. The food is not up to standard as they cook the same food most of the time. The area seems a bit unsafe as it is close to the prison. If you complain about the service the owner threatens you.
