Dear Sir,
We are continually receiving prperty penalties for unpaid tax, our building is 50 50 agreement between villager and builder, and 50 percent building is on rent. We try to pay property tax but many times it was refuse from nmmc by saying come all members together. And its looks like never ending subject.
