"An absolute joke!"

I had an appointment around 3 weeks ago. I attended but arrived 45 minutes late, this was due to an accident on the motorway which I had no idea of at the time. I asked the receptionist for an appointment he just told me to ring up. I have now been doing so every single day, all I get off the phone is ' we are receiving a high volume of calls'. I left my details as asked and still had no call back. I received a letter saying I must make an appointment as the dental hospital won't be responsible for my braces! I contacted the switchboard and they transferred me to the manager so I could complain. Now I'm waiting for a letter or phonecall in the next week. It has taken all this to try and get an appointment. Something needs sorting!
