IGL — meter replaced but still billed for old meter no. reading

Address:

Ghaziabad, Uttar Pradesh, 201014

My IGL Meter was replaced on 20th Feb 2018. I have so far received 2 bills after the meter changed and both bills are incorrect. Both bills are for the old meter no. and the readings are also incorrect. I have opened several Service Requests and sent WhatsApp messages to IGL but still no one have been able to fix a simple problem. They just need to remove the old meter no. from my BP# and add new meter no. in the system. However no one in IGL is able to make this simple change.

I am tired of calling IGL customer care and explaining them this issue.
