Greater Noida Authority — pending water bill

Address:

G-350 Gamma-2, Greater Noida, Gautam Buddh Nagar, Uttar Pradesh, 201308

I purchased plot no. G-350 gamma-2 alotee number - g0120500, named shilpa sharma in april 2018.
In this year i received water bill of approx 8000 rs, including 6 year pending water bill.
How this is possible when i purchased plot in april 2018 after proper property transfer process - how this pending amount remaining. When i talked with old owner - he told me that he completed all dues.
Due to authority mistake, always customer like us suffer.
