Mahadiscom / Mseb / Msedcl — I am complaining about wrong amount due has printed in bill

I got the bill at the date of 8-1-2022 but when I check the bill. printed amount on the bill is 660 but when I calculated the unit with the rate it shown another amount unit used is 94 and according to the rate table which is given in the behind the bill it shows if it is between 0-100 then the rate will be 3.44 so after calculating the amount is 323.6 not 660 but why its showing more than expected amount.
