Aptech Computer Education — fees refund policy not visible for public

I paid 17500 rs for softpro android for my sister and my sister attended only 2 lectures. She want to discontinue admission, so i called branch manager to check on the refund policy. He says the please send an email so that you wont get botbere for further installs and you paid fees is non refundable because he tells that my sister has already recevd email login credentials which she hasn't recvd on mail. When i said that to them they say that email id written is wrong which is false cause i was present when form was filled. They disconnected call twice in the middle of conversation being afraid at fault.

Now i dont know where to find justice as fees paid is a very big amount.
