Ufaber Edutech Private Limited - Fraud done by the company

I joined ufaber edutech as an online work from home English trainer. I was told that I need to pay Rs ***** to them for the training of * courses. I convinced them to pay the money in instalments and paid Rs **** as my first instalment.
They provided me with *-day training of only * course and after that gave me a few students. Soon after that, I started getting calls from them to pay my remaining instalment of Rs **** but I asked them to at least start the training for the second course and when it starts I will pay the remaining amount as I was not getting more than *-* students. I was worried about my investment. They never gave any reply about the training on other * courses and just said that out of three courses * are almost similar.
After *-* months I was finding it very difficult to recover my amount and earn money. I started asking them to give me work because they promised to fill all my available slots with students. From the month of June, I do not have a single student and when asking them the reason on emails and messages they just blocked me from everywhere without giving a reason. I also got a call from their employee Ritu Mishra who spoke to me very rudely and abused me and just hung up the phone. I kept emailing them asking me to clarify but they only sent * reply that you are fired. I tried a lot to contact them but they never bothered to reply.
I want a refund of my Rs **** as I was only trained for * course charged **** for it and compensation for all the time they have ignored me. I have wasted a lot of time trying to contact them and to find out the reason for not giving students.
My whole routine and my income got disturbed because I am women and my basic expenses were depended on them. Kindly take necessary action against them as they are fooling housewives in the name of giving jobs. I am also in contact with *-* women who are also suffering like me.
