Is this reference correct about IFSC? https://www.hdfcbank.com/personal/resources/learning-centre/digital-banking/what-is-an-ifsc-code
Now if you identify the error yourself, how do you draw the conclusion that this is bcgame's fault? If I understand the reference correctly, IFSC should be the user's self-written data in the payment info page. Most casinos can't help mistakes that are basically made by users.
