State Bank Of Travancore — Debit card not received

Address:

500016

I requested a debit card on 1st March. On 4th March I received an sms (in fact four sms) stating the my card has been dispatched under tracking number xxxxxx by speed post.
I have not received the card yet.

I have tried to track the speed post from 5th March, every day it says that the details are not available in speed post system.

Surprisingly I received the PIN from my bank, which also came there by speed post. But they don't know anything about the card, it is said to be from a different source.
