Dear Sir/Madam
I am facing a refund issue with IOC (Indian oil corporation)
Registered mobile number: [protected]
Consumer number : [protected]
Agency name: Selvi gas agency, porur

I booked indane gas cylinder on 12-July-2023. On the same day, the invoice is generated. After the invoice is generated, i have paid the amount through online.

Since, the invoice was already generated as cash, i contacted selvi gas agency. They said they did not received the on-line payment.
Also, they advised me to cancel the booking. And i cancelled that on 15-july-2023. But, the amount i paid is still pending to receive to my account.

I also raised complaint for the same twice in IOC website. IOC customer care saying there is no amount credited to IOC account without checking the bank statement.

I contacted ICICI also multiple times, they are confirming all the time that the amount is successfully credited to IOC bank account. Also, they are giving me the RRN number for reference.

Bank is saying the amount is credited to beneficial account (IOC).
IOC is saying that it is not received.

But, There is no one in IOC ready to check IOC bank statement with the transanction ID/RRN ID shared by bank.

The following is the confirmation given by bank.

"Dear Customer, Your transaction of Rs 1118.5 from ICICI Bank was successfully credited to the beneficiary IndianOil Corporation Ltd account XXXXXXXXXX9643 on 12/07/2023 16:27:41 with RRN[protected]. In case the beneficiary has not received the amount, then please share the reference number with the beneficiary, to check with their bank."
Below details are given by bank:

Payee Name IndianOil Corporation Ltd

Payee VPA [protected]@hdfcbank
Payee IFSC HDFC0000079

Need IOC to check and confirm the same and need refund for the same.
