"Clueless"

Referred to rapid access for chest pain and ecg abnormalities in may 2016, told I would have a diagnosis and a clear treatment plan after this appointment. Now into November 2017 and still do not know what is wrong, what treatment may be required or anything. Received a letter today informing me that the appointment I was sent 5 months ago for next week has been cancelled. No alternative appointment offered. So will be around 2 years after my initially urgent referral before I get any clue what is wrong.
