HDFC Bank — I am upset

This is the 4th time i m complaining. I requested ecs to be stopped from my account. The only ecs i wanted was from yes bank. Priya Nair from Mind Space requested me to submit a letter and ecs stop form. I did this nearly 7 times in mira road shanti park branch from september last year. The girl at the branch laughed at me and said we have earned 65000 from you. Today 1000 was cut in ecs and the rest fees. I am a heart patient and need that funds for heart surgery. They are least interested in helping me. I am sure they have torn the letters and forms to steal from me. I had to leave my work. All this is causing me stress and chest pain. Nadia from hdfc bank asks me to click a link which is unacessible. Then she does not reply. If something happens to me hdfc is responsible. My customer id is 22840860. Hdfc is a fraud. If you do not return the ecs charge fromseptember i will file law suit and put in social media.
