Calcutta Electric Supply Corporation [CESC] — not generating the bill for february'19

Sir/madam,
After my transfer to delhi in 2009, my mother was staying there. However, due to her health conditions of old age related problems, she could not stay alone there, leaving the flat vacant since january 4, 19.
Being an obedient indian citizen, i regularly pay the bill as and when generated either offline or online.
However, this time (February'19) when i wanted to pay the bill through online, it is seen online that "the bill for this consumer number has not been generated yet" reflected in the bill details. It is not generated perhaps due to no use/ non-consumption of electricity since my mother's shift from the flat on 5.1.19 and it will continue in this way except my visit to the flat sometimes during my leave period till transfer back to kolkata.
It is therefore, requested to kindly regularly generate the bill of my ca no.[protected] ([censored]al chandra ahikary, b-35/002, peerless nagar, sodpur).
