Andhra Bank — Misbehave done by bank manager to a senior citizen women

Address:

B-3 62/46 Karkhana Bahgwan Dass Hoshiarpur Punjab

My name is Seeta Rani. I am resident of Punjab Hoshiarpur . My bank branch is Shimla Pahadi Hoshiarpur. I have been Andra Bank's CUSTOMER since 20 years as of now. All of my family members have accounts in your bank.
I had a business limit with Andra Bank which was approved in 2015 for 2.5 lakh INR. I was paying all the installments and in 2018 I paid it off completely and closed the limit. After closing it I confirmed with that time manager name Anindya Sarkar and he told me everything is done and I can destroy the pass book.
Since then there was no transaction done from my saving account for that limit.
In March 2021, all of a sudden from my saving account 2700INR was deducted and I was not notified for the deduction before.(as I used to get before for any transactions )
I visited the branch to ask for the reason for that deduction .The manager named RANJIT SINGH was very rude and unprofessional while talking to me and explaining me the reason.He said this transaction belongs to the limit which I had in 2015. When I explained him that it was closed long ago he started shouting and yelling at me.
As I am a senior citizen I asked him if he can explain this to my daughter over the phone but the threw my phone away and my phone broke.
When I asked him that I was not notified for any transaction he said I don't have time for all this ### and he asked me to leave.
He is working in the bank to serve people like me. Because of our accounts he has that job and he should know how to treat a senior citizen woman.I will never appreciate this kind of behavior at all.
My request to you is you should look deeply into this matter and take an action against RANJIT SINGH.
I will be thankful to you.
