Checking account Problems caused by my funds being low Florida

my bank account with 53rd bank, routing number - and account number ending in - was given an overdraft coverage for my withdrawals with a per-overdraft-item charge of $37.00.

Suddenly the bank cancelled this coverage without given me a proper notice so that they can return any over-drafting-item and still charge me $37.00. Please l need to know how legal this is and would like to know how l can get all my money in these charges back? I will provide all relevant information necessary for this investigation if need be
