Skill lync - Cancellation of Skill lync PG course

I am writing this because I am not getting any resolution of my issue from Skill lync,
* months back on june****, I have enrolled in a course of skill lync "Post graduate program in High Rise buildings design & analysis",
They asked me to pre book the course, I paid *****rs for that and they said you can start your course whenever you feel like to or after a month, and one day I got a call for documents and all, I provided as required, I was not aware that it will be a third party loan, I thought skill lync is providing an EMI facility, I was not aware or being informed that they will start the EMIs even if I don't start the course, I needed some time to think if I can afford the course or not, but they did not asked if they should remburse the loan and start the EMIs, I started getting calls from Skill lync finance team and eduvanz for EMIs even when I have not started the course and still since the day of enrollment I have not started the course because I cannot afford it, I cannot pay the EMIs, I have been requesting them to cancel my course for two months and getting the same response that there is no cancellation policy which I have not been informed about, there was no such thing mentioned about "No cancellation policy", Somehow I paid the first EMI to save my civil score and I am not asking for refund, I don't want the money I paid, I just want to cancel the course but I am getting the same response I don't want the money I paid, all I just want cancellation, this is my humble request to Skill lync, please don't do this, this is unacceptable. I cannot pay the EMIs, I don't want to Continue the course, please cancel my course. I am getting frustrated of continuous calls from Skill lync and eduvanz.
