"Endocrinology - appointment rescheduled 4+ times"

I started treatment in the hospital in 2016 and was referred by lewisham to kings college to a test in March 2017 (after kings college gave their opinion that I should be referred). I was meant to follow up on my results in lewisham in April 2017 (test results were stated as borderline) and have since then been rescheduled. Each time Its getting closer to my appointment I get a letter stating it's been moved to a few months time, and I've now received 4-5 letters rescheduling. My next appointment is not for another few months - I've been left clueless what my results mean and have to wait OVER A YEAR to discuss results from a serious test and what they mean/what my options are. It's quite frankly shocking.
