"Frustrated trying to contact Orthodontics Dept.,"

After my son had his wisdom teeth extracted we were very satisfied indeed with the service. The dental staff including the nurses, anaesthetist, the dentist and the recovery team were exceptional and extremely attentive. However we have become increasingly frustrated with trying to book a follow up appointment for a brace to be fitted in the Orthodontics Department. On many occasions we have phoned the Orthodontics Department and the phone is never answered. On two occasions the phone has been answered, and we have been put through to Orthodontics the phone call has been cut off! This is very worrying as my son really urgently needs a brace fitting as he temporarily has a chain and stitch attached to his cheek making it difficult to eat and clean his teeth. Also the chain and stitch has repeatedly come loose and has had to be re-attached, which is time consuming to say the least. We urgently need an Orthodontics appointment. Please help. Is there any way we can make sure we get an appointment booked, as this is now urgently required.
