ICICI Bank — Savings account frozen

My account has been frozen[protected] without any intimation. I have reached to the nearest bank branch (Rukmini gaon branch ICICI Bank) with my id and shared all the details regarding my daily routine online transactions. They were not able to provide a satisfactory response and were unable to unfreeze the account. I had to submit an application mentioning my salary account details as well (axis bank) along with my office address; however, i failed to understand why in the first place it is frozen. Even after submitting the application; they were unable to tell me when it will be unfrozen.
