ICICI Bank — charges for minimum available balance

Address:

Mumbai City, Maharashtra, 400069

Icici bank charging unnecessary amount as minimum available balance (Mab). My account was inactive since last 10 yrs. Now whatever amount i deposit, they deduct it as mab. Online complains resulted in answer to visit home branch. I visited home branch i. E. Andheri mumbai. They are not ready to listen and simply demand for more money to be deposited. I don't know what to do.
