Bajaj Finance — Refund required

I have taken personal loan of Rs.46, 000. I have told the agent to keep the loan due as 24 months but he has kept it for 36 months. That's the reason I have cancelled the loan and I paid the amount in the cash counter.

But now I got my 1st emi deducted. Can I know why?

Can you please refund the amount and close the loan.
Update!
