Citibank — Regarding credit card application status

Address:

Pune, Maharashtra, 411002

Hi,
2 weeks i got a call regarding Citibank credit card based on their request i have provided addhar card, pan card photocopies and salary slip . then on next day i got their call asking address where i want my card to be delivered . i have given that information then they told me that i will get a verification call in next 2 days . but it is a week now, i haven't received any verification call . Then application number received receipt shared by representative is having application number of length 10 which is showing invalid when checked on online portal . they required application number of length 11 . I would like to check whether my application is correctly received by Citibank or it is fraud ?

Thanks
Kedar
