I've paid fees to a private medical college in India, but now I want to get a refund and my original documents back. What's the process for doing this? Could I file a case in consumer court or are there other options?

Yes, recordings, voice notes, SMS, emails, and WhatsApp messages can be used as evidence in a criminal cheating case under IPC 420 in India. However, their admissibility depends on factors like authentication, relevance, and compliance with the Indian Evidence Act. The prosecution needs to prove that these digital records are genuine and related to the alleged cheating.
