Sir,
This is regarding bp no. [protected]. I am fed up with the igl customer services. I took this png connection in feb 2019 for that i received a bill in apr 2019 on my registered mail id. It was a estimated bill of 791/- not actual bill, no meter reading was shown. After that i am waiting for my next bill till now. No meter reading uptil now has been taken, and when i asked they noted down the meter reading verbally. Now, my bill is generated but they are not able send the same on my registered mail id even calling them no. Of times. Customer representative are very pathetic and disconnected the call no. Of times without resolution. If i could not see the bill, can you tell me, how will i pay for it. And if the last date gone, i am not going to pay any penalty amount. Please make note of the same. Do some hard steps on the same.
