Meritnation — I am complaining about Bajaj Finserv and and meritnation

I took subscription of 95000 of meritnation on EMIs through bajaj finserv of ₹5459/ month. But it started to deducting Rs. 590 extra at least in 2 to 3 times in a month. I told them to cancel my subscription, but they told that they have NO CANCEL NO REFUND policy but before subscription they didn't told something about this. They also ignores our complaint and don't helping us. Please help me I am a student now I am very disappointed regarding this because this is collapsing our economical conditions.
