State Bank Of India [SBI] — Failed BHIM money transfer, the amount is NOT reversed to my account.

Hi,

My name is Tomsan K. My SBI account number is [protected].

I transferred ₹4, 000 to one of my friends' account on 1/Sep/2021, the customer reference number of the transfer us:[protected]

I was told that the transaction is timed out. On the 3rd of September I raised a dispute, it still shows that the dispute is Open.

On the 7th of September I lodged a complaint on NPCI 's website and all that I received was a message: Your complaint number is "1301563"

How to get back my money?

Regards,
Tomsan K
