State Bank Of India [SBI] — credit card bill payment reminder even though card is cancelled

Hi i had got a cc frok sbi and i did not activate it as the credit limit was too low. Contacted call center and then cancelled it as i got a message that processing fee of 500rs needs to be paid..

The call center also agree to cancell the card.

Now i'm constantly getting message to pay the cc bill. I dont even know the credit card number and i disposed it. Why should i pay when i didn't even activate it?

I'm getting a message that an amount 3k needs to be paid.. I have no idea about it.. Tried contacting the call center again however not able to go through the ivr

Please help
