Tamil Nadu Electricity Board [TNEB] — Discrepancy in EB charges

Address:

Hubhadhali Eb office , the nilgiris

Sir
The Eb charges has been raised Rs.1130 Comparing to previous bill. Same was enquired in concern eb office . They are saying due to Covid based on the previous bill, amount has been calculated. If it is so the amount should be less for me . And also need to check my EB meter, it's shows higher consuming since the consuming unit is less for us since we were out of station for the two weeks.
Thanking you
