Classes not giving refund.

Hi,
I have joined offline classes in March 7th 2020, and paid the money through an EMI aggregator which has tieup with the classes. I'm paying the EMIs for 63720 /- INR but I'm not getting offline classes due to COVID-19 situation, classes have shifted online and they are asking me to wait for offline class until there is any directive from government to start the class. I had attended only 2 weekends from 7th march - 15th march, then they went online. Now the issues is I'm only 2 EMIs away from completing the loan but there is no assurity as to when the offline class will start and joined the only because of offline class, I am not able to keep pace with online class and notified the same (I attended 1 or 2 weekends online before notifying them) they asked to wait for offline class. Offline is being pushed and I am being said to do online which I am not comfortable with and asked for refund which they're denying since it's too late for that.I want offline classes but there's no assurity when it will start, is there any way to get refund? I have kept every calls in recording.
Please share your thoughts on how to get refund or what would be the best approach to get money back.
If required I can share the T&C as per their website.

Thanks.
