Crio Support India Private Limited - Refund the amount

They get me to attend the summer course of web application course of around Rs ****** total fees. I agreed first by that course so I paid Rs **** for booking my seat. But Suddenly I changed my mind to attend it so I asked them to refund the money but they denied to give it back. I haven't attended a single lecture and after paying the fees * to * days later I informed them to refund the amount I paid but still they denied . I want my amount back. Here is google drive link that contains the address of the evidence that I paid the amount . https://drive.google.com/file/d/*aB*-YGiB*mZIgUyHhXYJtLN*x*-Jo*G*/view?usp=sharing
