Skill vedanth - Course not given even after full payment

I had received email regarding the course from Skill Vedanth through my Institute email id. I applied for *Full stack Web development using AI* in their Google form and received call from their side and had paid the full amount of the course i.e. **** on **th January ****, them saying that students of IIT gets some discount. Their counselor Akshita Das, contact - ********** guided me through registration process.
The course was to start at *th May after the induction session but even after that, no course had been updated in my portal. I tried to reach them through WhatsApp many time regarding this but they all either left my message unread or didn't respond.
This is a clear harassing as a student, misusing my Institute mail id for such scams and not being responsible for my payment.
They had promised live classes, projects and internships but not a single one has been fulfilled.
And now, Akshita Das' number is been said to be deactivated.
Another one of them was Sravani Ma'am, contact info - **********.
My Slot number was - *** and Enrollment number - IITH******INT.
