"very dissorganised"

I first had lung cancer in 2014 , was waiting to see lung cancer team from London, who stated they lost my files for 3 months, ,after the op at London I was told I who been seen over a 5 year period every 3 months for the first 4 years then 6 months on the 5th year, a joke my appointments over 2 years have been 7 months and 8 months apart ,now they think cancer is back was supposed to get results fro pet scan ,on 11th of January 2017, but evening before the appointment was cancelled ,no new one as yet I don't think they see they are playing with life as cancer can spread fast July 28th 2016 has a Stemmi heart attack , was given 3 stents then put on a trial drug that I was never told it was a trial , had bleeding was taking in for a blood transfusion , only then the medical doctors told me the drug was dangerous and I needed to stop taking it , it is wrong they don't tell you anything . to this day I have had no explanation , and I can assure you if cancer is back I would not want to be treated there again would rather die as I have no trust in the care given as they have no care and receptionists should not play god with appointments as they don't know what is urgent or not , sad place for any one to have to go to .
