Bank Of Baroda — Excess charges in credit card

Address:

Flat no 409, Raghu Towers, Leela mahal Uproads,, Income tax ofc lane, Dabagardens, Income tax ofc lane, Dabagardens, Income tax ofc lane, Dabagardens

In March month bill - there is one line item stating that excess amount reversed Rs. 30, 000 dated 12th july 2021, i raised a concern of it with the bank and 2 escalation requests also raised.
After that i received a reply but bank never told me the exact issue, So i kept that 30000 on hold for 3 to 4 months and the bank treated that amount as part payment and charged charges on it.
and the amount mounted to nearly 59000rs.
then i raised a compliant with RBI, those guys called after the compliant raised with RBI and stated that the amount related to bill of September and closed the compliant.
I Agree that the 30000 was excess credited in September, for that i am responsible to pay, but the charges mounted on it makes it to 75360 rs. the extra charges are to be reversed as the bank is failed to provide the information to my 7 mails. and further in one mail they told that amount will be reversed. if the bank provides the data in april itself then i pay in april itself.
further to that it was banks technical issue in September for excess amount, then they should provide the data in april itself saying that it is related to september bill and all, now it became burden on me and effecting the creditscore.
