TalentSprint — Regarding taking loan on my behalf

Address: no address mentioned in brochure

I joined a course named ADSMI held by IIT Madras in association with talentsprint. The brochure of the course was shared to me on whatsapp by a girl named Bhavya who was in talentsprint. I was told that the course will be held on saturday and sunday and I can watch the video of the class uploaded later on the ADSMI platform. It was mandatory for me because I am a working professional and my saturdays are working.
Later when I agreed to join the course they told that I have to either pay full amount or in monthly installments at 0% emi. 2.5 lakh was a huge amount and I am a middle class working professional so I opted for monthly installment. They asked 26000 for seat allotment and then they asked for my id proofs and bank statements through whatsapp.
When classes started then they told that 75% attendance is mandatory for certificate and classes were held on saturdays and assignments on sundays. I requested talentsprint to held classes on sundays as I was missing classes and was not able to keep up the attendance with job. I joined for 3 months and paid 3 installments too from a payment link shared by them. But then I was not able to keep up the course and knew that I will not get certificate due to less attendance so I requested talentsprint to deregister me from the course and as I am not that much financially strong so I will not be able to pay the fees further if I am not doing the course.
Then I came to know that with my documents they took loan on my behalf from a company named liquiloans. They took the whole money on my behalf and now they refused to stop the installments and pay the money back to liquiloans. After that liquiloans is threatening me and my father with different numbers on calls and whatsapp. I requested talentsprint regarding this but they said that they will not take the money and now I have to directly deal with liquiloans as my documents were used for the loan.
Liquiloans have tortured me and my family with calls and messages and they have issued a lok adalat notice mentioning that I took an education loan from them and they are not even mentioning talentsprint in between.
Many lawyers are calling us and threatening us for money.
If I was so financially good then why would I have taken monthly installment option so how can talentsprint take a loan with complete money on my behalf and now refusing to return the extra money to liquiloans.
Loan is taken by talentsprint so why is liquiloan mentioning my name on lok adalat notice for educational loan.
Liquiloan even called few contacts from my phone and told them that I took money from them and I am not sure how did they got those contacts. Are they hacking my phone?
The brochure does'nt even have an address of talentsprint.
