Greater Chennai Corporation Property Tax for 2024-25 (2nd half)- Letter from Tax Collector

Vanakkam Chennai Makkale!! Anyone receiving letters from corporation office stating the property tax bill number and amount of property tax due and asking you to immediately pay?? Initially i thought that we had not paid for the 1st half for 2024-25. But after checking the portal, we have already paid for 1st half and the due date for 2nd half is 31st march 2025. This kinda communication is new for us as we generally receive a message. Has anyone received this kinda messages last year?
