"Wait times for surgery are unrealistic and not..."

I attended an assessment with a dental consultant in August 2013, and I was told I would receive surgery within 18 weeks' time. As I write this review I am still waiting for the promised surgery. First, the phone number on correspondence is incorrect, and I have to make repeat phone calls in an attempt to discover what is happening with my surgery; I find the lack of correspondence appalling, especially since the correct phone number is rarely manned, and mostly goes straight to answer phone. Through my efforts in ringing the correct department, I was finally offered a pre-op assessment, which I attended on 29/01/14. My surgery was booked for 11/02/14, but was cancelled the night before this due to A & E pressures. I was promised the next available appointment, but as yet have heard nothing further from the hospital, and when I ring up the lady dealing with my consultants cases is unavailable. I am now around 27 weeks into an 18 week waiting time, with no end in sight. Once I eventually receive a second appointment I will have to attend a new pre-op assessment, which will cost me time and more extortionate parking charges. The nurses and staff at the pre-op assessment were very lovely, friendly and helpful but the hospital targets appear to be unrealistic, and the lack of correspondence is appalling to say the least.
