"Appointment rescheduled 6 times and still not..."

I was seen by a consultant in Aug 2017 after being referred by my GP in June 2017. I require a minor procedure and so was given an appointment with a surgeon for Jan 2018. This has now been rescheduled 6 times and is presently for the end of May, coming up to a year since first presenting at the GP. If the appointment keeps being rescheduled I think that we will probably looking at a more involved procedure. I have already contacted PALS on there appropriate contact email with no response.
