"Phone lines have a serious problem. follow up..."

I called the antenatal clinic at 8.30am as soon as they opened can some explain to me why i am still on hold at 9.30am if i have been the next in line since 8.30am? This is not a line to speak to a consultant or a crisis line. It is a booking line. You should be able to call the line and a maximum of 10 minutes be off it. Why does it take so long to schedule an appointment. This is ridiculous and unacceptable. The mid-wife i met for my first appointment is the only reason i have not asked for my hospital to be changed.
