They have no e-mail address, and no way to contact them through the BIDMC patient portal. They never answer phone calls, unless you can wait for AT LEAST ONE HOUR. Even then, they often hang on you. Unless you go IN PERSON, it is impossible to book an appointment or change an appointment. This is extremely bad and unreliable.

ONE HOUR ON THE PHONE, and I can't cancel the appointment. What your line is for? Having a coffee all day?
