Never answer the phone
I called a couple of days ago and they said I needed to call back at 8am to arrange an appointment. At 8am on Tuesday I called them 25 times. Each time clicking '1' to speak to a receptionist and each time I've spent 6 mins on the phone for it to automatically hang up. Needless to say I've also gone down at 8am previously to be sitting there for over 2 hours and having to leave to collect my daughter from nursery. Very annoying as I need a check up and new contraception and I can't arrange an appointment to do so.
