Tamil Nadu Electricity Board [TNEB] — Advance payment not credited to my account

I am Arun from Old washermenpet, Chennai.

Consumer No: [protected]

I made my EB payment RS 50 online and then paid advance payment RS 3710 for future purpose. The amount of Rs 3710 is debited from my account and credited to TNEB account.

Now the advance payment is not deducted from my recent bill.

Kindly help me to get my money back.

I have attached the screenshot of my statement for the proof.
