"Lack of service"

I have made a verbal complaint about my treatment or lack of treatment from your Ophthalmology department. Following a telephone call I was promised that you would contact me with an explanation. In short I was referred to your Clinic in late October 2013. A number of phone calls were made to try and expedite my appointment. In late January 2014, my wife took a phone call from you asking whether I would be in attendance for my appointment that afternoon. We had no knowledge or correspondence regarding this appointment prior to the phone call. Then I received another appointment for one afternoon in late March 2014. Again I made a number of phone calls without success. Finally I talked to someone who had been recently appointed who told me she would investigate and let me have a response to my complaint. It is now 1/5/14 and I am still waiting. During my initial examination by the Boots Optician who made the referral I was found to be unable to see from my right eye. How long are we expected to suffer this sort of blindness? This is disgraceful and unworthy of what used to be a treasured British institution. In my opinion you should be totally ashamed of your conduct.
