Tamil Nadu Electricity Board [TNEB] — Defective Meter

Address:

LIC nagar , Madipakkam

My Name is Prabhakaran.
My EB servie number is[protected].
The EB meter was marked defective on Oct-2022.
There was no action taken place. I met the AE at TNEB madipakkam 7th Dec 2022 and gave my complaint letter it was promised that it would be fixed in 1 week. But no action taken place even after 3 weeks. In the mean time I tried to reach them by phone several times and went to the TNEB madipakkam office 4 times. But no action. I'm very much frustrated by the worst performance of TNEB and it's staffs. From 21-Dec-2022, I'm out of town. But the EB meter box is open so that it can be fixed.
Please take some professional action and fix my issue.
