Scam number from মাউশি [PHONE]

A few years ago, I received a scholarship, but some of the money remained stuck in the DSHE system because I had failed to submit my bank statement on time. Three years later, a man named Asad called me, claiming to be from my university. Since I was unavailable, he contacted my father and told him that he could help us recover the scholarship money. However, he asked for my credit card number to process the payment. At first, it sounded believable, but when he asked for my credit card PIN, I became suspicious. I contacted my university office to verify his identity, only to discover that no one named Asad worked there. The university staff informed me that this was a common scam targeting scholarship recipients. That's when I realized that the man was trying to deceive us and potentially steal our money.
