Sdmc — SDMC property tax

Address:

Assessment & Collection dept., Civic centre (20thFloor) J.L.Nehru Marg, New Delhi - 110002

I live in 53 Hemkunt colony and I am unable to deposit my property tax online. My UPIC number is [protected] whereas my wife Sushma Jain's property UPIC is [protected]
When I click on 'pay tax' option, on MY UPIC number, the screen shows my apartment details BUT with Sushma's UPIC number (i.e. [protected]) instead of mine.
Can SDMC amend the record at their end so that I am able to pay my property tax for MY property on line.
