State Bank Of India [SBI] — sbi credit card illegal late fees & interest charge

Address:

122001

I have been using SBI credit card since 2015. I was charged annual fee in April 2019. I called up the bank to cancel the card as I didn't want to pay the fees. The agent Amruta promised me that once I make the annual fees & late fees, they will reverse all the fees on the card. My reference number is[protected]. But in the May'19 statement generated on 14th May, I was again charged with a interest of INR 7463. I called on 27th May'19 & the agent, Sarenya informed me that Amruta didn't make any late fees / interest fees reversal & she just made a false promise. Because of that I have been charged a late fees.
I will not make this payment as I have not used this card & I will never use this card again due to the unethical measures adopted by SBI card company. My credit card number ends in 2641.
