"Waiting time for follow up appointments."

My wife was seen by a locum consultant on 09/05/2014 and was diagnosed with possible mild symptoms of Parkinson's disease. She had blood tests, MRI and DAT Scans and was told she would be seen again in 3 months. She has not been seen again and despite numerous enquiries no appointment has been forthcoming. At one time she was told as she had been seen by a locum who had now left the hospital she could not be seen until another locum had been appointed - really!!! She has been given various assurances that an appointment was imminent nothing has been received - this despite her GP writing in regard to this lack of appointment.
