Appointments in Hospitals

I was referred by my doctor for hospital treatment, he said I would get to choose my hospital but not with him. I was given a leaflet that explained the CAS which would manage my referral. I called the number on the leaflet but they had passed my papers to another doctor for a second opinion. The second Doctor agreed with my own doctor that I needed to be referred to a hospital.

The CAS lady called me and was very nice and asked which hospital I would like to be sent to but clearly she wanted to send me to Northwick Park Hospital. In the end I accepted, the hospital is at least close. I was given an appointment within 4 weeks and was pleased so far, the appointment was cancelled wrong department and I was given another appointment only two weeks after the first appointment, I was still happy.

I arrived and was told this was not an appointment for treatment but for inital assessment by the hospital, I presume to make sure my doctor and the second doctor that I never saw was right. I was given another appointment this time at another hospital in Park Royal miles away and it took ages on the bus and train to get there. The service was good but the travel was bad and I would have preferred to go to a different hospital in London than have that travel to Park Royal.

People say I should be pleased with being treated and I am but: -

Why if we are supposed to get a choice, do we get pushed to a CAS choice?
Why having accpeted the choice that was pushed do we get sent to a different hospital?
Why did my doctors opinion need to be checked by a second doctor?
Why does it still take 6 months from seeing my doctor to being treated?

Am I the only person pushed about by the NHS in Harrow.
