Upgrad — Uprad not refunding my money

I applied for the course post graduate programe in Al and ML, I paid 15k for booking the seat but due to some financial issues I applied for the refund. So it's been more than two months now I applied for the refund but haven't got my refund yet.
Now I have already sent more than 30 mails to [protected]@upgrad.com but they are not willing to understand my problem and not paying back my money.
All this happened because of my admission counsellor Sarthak rajawat, I applied for the course on 11th of September and I applied for the refund on 13th of September i.e. just after 2 days, so just after applying for refund, the upgrad team told me that I would get my money back within 30 working days. After that I was trying to reach my admission counsellor Sarthak to check my update on refund but he was not responding my calls, my watsapp messages. Suddenly on 28th September he called me and said that he is going to help me on my refund process so that I could get the refund quickly. He said that he is going to cancel my refund application and he is going to do it in his own way as he had done a lot of refunds. I believed him because he was from upgrad and that was my biggest mistake. He said that he needs my permission to cancel the refund process so that he could restart again which I applied earlier and said that just respond "ok" in the mail which he sent that day, so I believed in that upgrad guy and replied as 'ok'. And after that suddenly he disappeared, he did not picked my calls after that and the refund team is showing me that mail in which I said "ok". I told them that it was your guy who misguided me in doing such things but they are not listening and now they are not willing to pay me my amount.
My financial condition is not good and that's the reason why I applied for refund but upgrad team is not understanding my problems. Can I get any help here..
