I have found the staff hard to get hold of. Calling their switch board inevitable bounces you to a voicemail of someone.
Requests for maintenence often seem to go unheard. Then you will come back home from work to find that what you asked for has been done without any warning.
So your request was made by voicemail, never confirmed by even a quick call back, text, letter or email, and then some arbitrary contractor will be handed keys to your property without your knowledge.
Very unsatisfactory service since I paid them my money.
