"The worst hospital in all aspects"

Hi, I'm from Europe, young guy lucky still alive, in Covid 19 period stuck in UK, and suddenly had a problems with heart(chest pain) and I'm absolutely scary what bad health care system is in UK, what a unskilled peoples are working in Hillingdon hospital. I came to hospital in very bad condition with neighbours help, because hospital did not want to send an ambulance( when I came 3 ambulance was empty) I came to hospital with 147 blood pressure(normal is 120) also I had wait in que an around 4hours, so long story short they give me a pain killers, paracetamol and said that I can go home and this is absolutely shocked me. Thank god I'm on the way to my country still in bad shape, but one thing I know, that expierence with UK health care was stuck in my head until the end of my life. I will never recommend to any kind of people trust with NHS garbage system and if you wanna be alive just go to other places or private clinics.
