Very unprofessional manner on the phone, not at all helpful. Demanded a guarantor even though I am well above the affordability, then when I didn't have one he basically hung up the phone on me. I have worked in Lettings for many years myself and know that you only need a guarantor if you are do not meet the affordability requirements. Can't imagine what their management service must be like if this is how they are on an initial phone call.
