Update: I got both the cards. I have only activated Ashva.
If someone was waiting for automatic card closure if not activated within 30 days as per RBI Guidelines. That might not work in the case of IDFC as per my experience. IDFC charged the JF instantly and they are treating the card as active as you have applied the card. The billing date for the card is 22nd September, so it would be a good idea to close the card before the bill is generated if you do not intend to activate it. Read the comment.
Actually you can ask IDFC First bank to remove the entry from your CIBIL, RBI has clearly mentioned that if bank added a credit account before card activation, they have to remove the account from cibil within 30 days.
Update: I raised the card closure request on 7th Sept when I got the Cibil account added notification. Initially, the card fee reversal request will be processed, then the closure request. Was waiting for the update on the 13th I called the CC and asked for an update and requested to arrange a call back from the senior as the agent was unable to provide me with...
@Krishna Kumar any update on your fee reversal request?
