Not Sanction Indusind Credit card

Location/place: Mumbai

Hello,

I have applied for a Indusind Credit 2 weeks back.I have submitted all the required documents in the same day.
They called me twice for some confirmation and verification.

Today i got a SMS stating unable to sanction your card.

I called them thrice to ask the reason.They didnt picked up.
They have just cancel my request without informing me.
