Small iranna wasti opposite of government godawn solapur - 413001

I am taking loan from sbi solapur branch on July 2019 of Rs. 5, 40, 000/- at the intrest rate of 12.4% and installment of 60 equal months as per my loan agreement but after 4 years I am pay emi on time even in such a COVID lockdown situation I am pay all the emis but now when I visit bank to close my loan after 47 emis I am calculate my loan amount and arrange the money to close the loan then I am shocked they said your loan not for 60 months it's a 72 months emis they say and amount is much more than my expectation then. I am raise this question that I have agreement of the loan there are clearly mentioned that my loan is 60 month installment but now their system shows 72 installment how this possible I am said to manager they are told about RBI Guidelines for this i am said that how the loan will turn 60 months to 72 months even I have not received any of such this information about they change my emi 60 to 72 even my email is registerd my mobile no is registerd in bank even they are not contact me for this i am facing financial crisis and also I am paid all the emis my financial condition is not good. Now they are says your loan intrest rate is increases to 13.9% and they raised this to thier back office but even now they are not having to say how is this possible. even I am calculate this in the official website emi calculater of loan there are also I have seen that Personal Loan Amount

And my bank installment is Rs. 12, 130 per month emi they reduce in every month
