need help on yesbank charges for non maintenance of AMB

Hi all,
 
 Yes bank used to be my primary account, after moratorium I have shifted my primary account to hdfc now.
 But I had a tax saving FD worth 30000/- in yesbank with maturity on March 2026. As I have moved to hdfc, i rarely used yesbank. Later i got some mails stating to maintain minimum average balance, when i tried transaferring money to my account it was dormat, so i had to personally visit nearest branch and get that sorted and because of bank delay it took almost 45 days to get that cleared.
 
 Now I got a mail that i will be charged for non maintenance of the account, I could have transferred my money and left it if I dont have an FD. My only worry is that I have a running FD, pls suggest me what to do.
 
 Thanks in advance.
