urgent help needed regarding my education loan at sbi...!😭🙏(query)

i took education loan of amount 5.07 lakh(principle) during 4 yrs of technical course started in 2022. the interest of 9.4-10% kept on adding, but some interest amount was repaid by CSIS subsidy (in 3 installments 5.5k + 19k+ 32k) during these 4yrs of my course.

In recent days the outstanding amount was around 5.62 lakh and in accnt. statement the interest was getting added every month, so i planned to arrange money and repay it as it's interest(9.5%) is feeling high to me, and will repay to the source from where i arranged by my income in upcoming years(as i completed my 4th year now and will be joining company).

The problem is that at the time of closing this loan, upon asking to the loan enquiry maam at sbi branch, she said that -> "no, now the interest will not be paid further by any subsidy cuz u already got subsidy in 3 installments and it happens in 3 installments only usually". so, then i arranged money and repaid that outstanding amount (5.62 lakh) cuz my ass thought now everything i have to pay eventually so why to bear this 9.5% interest thing.😭

But today i got to know that the interest during 4yrs course+1 moratorium period is all (100%) paid/covered by the subsidy if i am in csis subsidy scheme.

My question is the amount that i paid extra(5.62 lakh- 5.07 lakh = 55k ) could be adjusted or reimbursement could be possible now after closure of that loan account ??? (the education loan enquiry mam is now saying that we don't have any access of this csis subsidy thing, like she don't have any way to know weather it was even claimable or not, and said it's not worth it to investigate this now cuz ur loan account is now closed, .... and upon asking for reimbursement she is saying- "it doesn't happens like this" and no strong confirmation same like as before when i asked her weather govt. subsidy is going to come now or not?)

so, as it was claimable at the time of loan accnt. closure, but due to the false communication i paid all outstanding amount can i get reimbursement, is there any possible way??..😭
