The Reality Behind NCH Complaints for Products Sold Above MRP Online

By Parthapratim Dash
Recently, I came across something that truly shocked me—and as a conscious consumer, it was hard to ignore. A well-known Indian newspaper, available in print for ₹9 (clearly printed on the physical copy), was being sold on its official digital platform in PDF format for ₹25 . That's almost three times the printed MRP! Curious and concerned, I immediately contacted the customer support number listed on their site. I asked why the online version was priced more than the printed MRP. The response? “It’s a management decision.” No further explanation . I then checked their Terms and Conditions, Privacy Polic y —every legal and consumer protection section you'd expect from a responsible platform. To my surprise, they were all blank or missing .  So, I took the next logical step. I dialed 1915 , the National Consumer Helpline (NCH), to file a formal complaint. I explained my issue in detail. The executive assured me that the complaint would be taken seriously and action would be ...

UPI Addicted? Think Before Accepting Online Payments Randomly

By Parthapratim Dash
🔔 Reminder: Think twice before randomly accepting UPI or other online payments.   ⚠️ There’s no proper way to verify if the sender’s digital payment is clean or fraud-free. If any disputed or fraudulent funds end up in your account—even without your knowledge—you could get dragged into legal issues, including account freezes. 🚫 Also, avoid transferring funds between your own multiple bank accounts or family accounts if the fund source is coming from multiple senders or unclear origins. If there’s any chance of fraud-linked money involved, once such funds are triggered, all connected accounts may get frozen. ✅ Always be prepared: 📌 Keep records of every digital transaction—receipts, agreements, bills, or any kind of supporting documents. 📌 Applies to both individuals and businesses. 📌 Say NO to accepting UPI/online transfers in exchange for cash from unknown people. Also, avoid unauthorized fund transfer facilities such as some cyber cafes, where many onl...
