Tamil Nadu Electricity Board [TNEB] — unable to view the service number in the website

Address:

600005

I was able to view my service number [[protected]] until last billing and make online payments, but unable to view now for the current billing of january 2019. When i tried to add the service number, it says invalid service number.

Please help to make my service number visible in the website, along with the historical payment details and to make payments before the due date.
