"Dermatology dept....."

My husband had an appointment Feb. 2017, saw a consultant and was given a prescription of cream. The consultant told us he would see him again within three months. Because we did not hear anything for six months I contacted the hospital, they did not have any available appointments? I continued contacting the hospital with no joy whatsoever. We were then given an appointment in June 2018! when we were going on holiday. I ad to cancel the appointment and was told there was not any available appointments until Oct 2018. It is now January 2019 and we are still waiting?
