I want to close my meter connection, as for closing any account it need to be clear all dues. So i have paid amount of rs 31949 on first week of august. After that i am visiting dhbvn's office to close my account but now they are saying their system can't take entry of my submitted amount because of some system error. Now it is almost 4 months since they are unable to resolve this error. And i am frequently visiting their office regarding my problem. But they are unable to solve this.
