Citibank — Charging the incorrect fees

4386 xxx0 xxxx 2197 - i have applied for personal loan through citibank app. Interest is around 11% rs. 7271 on monthly basis which is finally calculated as per emi calculator. Now i found on my 1st emi they are charging 391.63 rs. Extra as gst on my monthly emi. So now i have to pay 7271 + 391.63 = 7662.63 rs. Monthly. When i had applied interest was 11% but on payment now it's 16.5% interest. Now i could go with cancellation because they will add 3-4% closure charges.in this pandemic situation citibank is not helping to reliable customers they are cheating for loan charges. I had checked also charges of icici and indusind bank they are charging amount as per loan calculator and they are not taking any extra charges to customers. If citibank said 11% then they should charge 11% only, whatever the interest and gst charges that all should be included in monthly emi. Please help to solve this as i can cancel my loan for this wrong information.
