Can I cancel a loan application after signing?

On 9th Saturday, I was made to join an online platform called Crio.do. After took 6722 rupees as initial Emi, bank statement of last 3 month, Aadhar number and passport size photo saying its for their financial team .After that I got a mail from a private financial service called Eduvanz saying a loan has been approved from them. I have completed E-KYC from them. After that I check the reviews of crio.do and eduvanz which were bad. I also learned that Crio doesn't have cancellation policy and eduvanz doesn't cancel loan once payment has done. I called them on the joined day itself that I don't wish to proceed with them but denied it as they don't have a cancellation policy. My loan application with eduvanz have video KYC, agreement and naxt payment pending. Can I cancel my loan application legally and it does adhere with their policy? I didn't join onboarding of crio,so can I recover money from them if I wish to proceed with a legal file against them?
