Saraswat Bank — saraswat bank credit card blocked

Address:

Mumbai City, Maharashtra, 400027

After numerous follow ups from my side regarding the temporary block of my saraswat bank credit card, even after paying rs.800/- in cash, i received the following message from saraswat bank credit cards on 13th may 2019 (After 3 weeks):

Sir,
Greetings for the day!
This card cannot be activated, we request you to do the fresh application from the branch
Regards,
Credit card cell.

I really fail to understand as to why this card cannot be activated and i need to apply once again for a fresh credit card.
Please reply at the earliest.
Regards.
