I closed my D-mat account by giving instructions and payingall the dues as the brokerage was too high. I even closed my ICICI Bank account after completing all the formalities. ICICI Direct wants annual manitenance charges from me. I have sent many mail messages as well as written to them to stop sending their bill or any communicatio on ICICI Direct's activities on an account which is non-existent. However, they keep sending me bills. Will they stop their practice of extracting money on non-existent accounts and issuing very disturbing e-mails?
