IDBI Bank — idbi mab penalty fees refund

Address:

122001

Jitender kumar saving account ending 6728, railway road, subhash nagar, kataria complex, gurgaon, pin 122001, since 2005. I have one ppf account with this branch also,
My concern is my minimum account balance is always maintained of rs 5000+, but i recieved mail from the bank that penalty charge of rs 118 is de deducted because your mub of january 2020 is rs 4824, i really dont know why.. Without my concern they charge debit card renewal fees of rs 220 also, this is insult of your valueable and old customer. I need refund of my mub penalty chgs.
