Fake Prize / Gift Voucher Scam

I received a call from this number claiming that I had won a coupon and was eligible for a gift voucher, including a nose pin and 1 kg of silver. The caller then asked for my name, full address, and whether there was a post office in my village. This appears to be a suspicious promotional or potential scam call intended to collect personal information. I believe this number should be marked as spam to help protect others.
