Upgrad.com - cancellation of course from upgrad

I registered for a course in upgrad. And paid *****/- on * March **** as registration. Then they told me to take no cost emi loan from propelled to pay the fee in installment. I took the emi plan . Its of *****/- per month and started the emi from *th April **** .I also paid ****/- to propelled for the registeratiom of the loan. My first installment get deducted from my account. My course started from **st March **** and after some days I realise that the course is totally useless for me as I cannot understand anything and did not want to continue . I mailed to upgrad a lot of time . I called to upgrad also but they are not cancelling my course and saying that we cannot cancel and give you refund you have to continue the course. I am mentally very tortured and depressed as they are not supporting me and my concern . I also asked propelled to cancel my loan as I don't want to continue my course . Propelled told me that if upgrad send us the cancellation mail we will cancel the emi and do the refund also. But upgrad is not ready to support me . Please help me I am very disturbed and depressed also .
