"Poor standard of care"

After 3 years and numerous letters to the Chief Executive, i have not got an apology and the hospital have not answered none of my questions. I attended for an iron infusion the nurse did not follow the guidelines. She administered 'forced" and as a result my eyes rolled back in my head my Heart rate shot up ton184.. Over 3 years letter came back saying "i will pass it on to ? "From one Executive to another. Each passing the complaint to the next. I was never invited to speak to any one and in the end i lost trust and did not attend for a year. When some thing is wrong the patient wants to be heard, not fobbed off and an apology, see where lessons can be learnt. I want justice. My life matters.
