Calcutta Electric Supply Corporation [CESC] — request for refund or endorsement of excess payment

An excess payment/transaction of rs 16840/-was done on 28.02.2019 through my credit card for new meter installation charges. This excess payment may be happened due to internet problem or some other reason. Bank has advised me to contact cesc for the refund of rs 16840/-

But, the excess payment/2nd transaction of rs 16840/- has not yet refunded or endorsed in my account.

I therefore request you to look into the matter and arrange for the same

Regards
