"Excessive phone payments to hospital appointment line"

I am writing about the north herts nhs trust, Lister hospital, Stevenage. I received an appointment through the post and rang the appointment line to change it due to being booked on a holiday on the given date. The number was a local number for the area but I was kept in a queue to speak to some one for 61 minutes......My query was dealt with but when my phone bill arrived the call cost over £7. I checked with BT and they state its because its listed as a business call. The appointment line should be better staffed so you are not kept holding and paying before you have even spoken to anyone. You should also be made aware of the cost you are racking up whilst waiting.
