same happened with me when I opened Udaan account joint.
1st card came in primary holder name within 1 week. i thought well & good. then i took follow-up for 2nd card which they said it got issued, but failed to give tracking details. raised complaint for the 2nd card & escalated the matter from branch itself. finally HO got involved, they said the card i already had is of secondary holder. and that they're issuing one for the primary holder now, by blocking & re-issuing the original 2nd card in their system. finally got it.
