They are harrasing me for emi payment but at the time of joining they didn't even informed me about loan the agent or the person from skillync hurried me and he did the process and he didn't gave me enough time to read and understand terms and conditions and after continuing for * months I came to know that the course is not worth and it's not at all good...so I've raised a complaint to stop course...but Eduvanz people are harrasing me to pay emi...At first I don't know anything about them...How can it said to be loan when I haven't received any amount from Eduvanz to my account...They are harrasing and skillync is not responding to my mails... please help me with this issue...
