"Choose and Book"

I was refered to Addenbrooks Hospital to the Endocrinology dept. I was given documents that gave a reference number and password, also a phone number to book the appointment myself. For the last two weeks I have been trying to access the internet site of which is not available, I have telephoned and was told there are no appointments available, dont know when they will be and to go back to my GP. I have done this and my GP has now faxed the referral to the hospital and I am now in week three and still no contact regarding an appointment! I am very anxiious about the whole thing as I have previously had cancer and am worried it could have returned and the weeks are passing by and I feel that I am just banging my head at a brick wall. I did try to phone the hospital and was told they dont know when an appointment will be available I could be looking at months not weeks, how does this fit in with the 18 week patient pathway.
