My consumer no[protected] . I have got Rs:1912 INR as bill amount for duration - 18 July 2020 to 17 September 2020.
Due to Covid, we are not at home that belongs to the above mentioned consumer number for the past four months.
We are worried and tried approaching the persons who took meter reading regularly for the apartment and we are not getting any support from them.We are continuously reaching them for past one month and getting improper response.
So we didnt pay bill amount yet and this bill amount is very huge for us.To your point, We have not received this huge bill amount even when I was staying at my home regularly.
We are helpless and afraid how we received this bill amount for no usage.
Please assist on this.
