With regret i want to draw your kind attention that for the lockdown the meter reading for the last month and current month was not taken and no bill was received by us. Inpite of not taking the reading you have sent us a message regarding bill where the charges are unexpectedly high. How can you do such a thing without proper reading!! Please look into the matter and do the needful as soon as possible.
