Tata Card — tatacard damaged my cibil score

Tatacard dangerous and damaging my CIBIL score.
I had purchased a laptop from Croma in 2013 and Tata card executive offered me a credit card with no fees. And I realised Tata card with credit limit of only Rs10000.
Then I called Tata card customer care to cancel my Tata credit card and executive had confirmed that my card will be cancelled but seems it was not cancelled.

I have never purchase anything from Tata card nevertheless they charged me Rs 500 as annual fees.
Then I called again in Tatacard customer care. and again an executive informed me that I don't have to pay anything.

After few months I got an sms from Tatacard to pay Rs 3277.87 and again I had called customer care and I talked with supervisor and he confirmed that I don't have to pay anything as I have not purchased anything.

Then, today I have got the same message from Sbi card to pay Rs 3277 and Tatacard sent my name in CIBIL and my score is bad.

This time I called SBI and report my problem.
And I got below message from Tatacard.

( Cardholder, your request for settlement of charges SR#[protected], on card no.ending XXXX2520, has been initiated. The same would be closed within 10 working days.

Hence, Croma is not good.
If you are an educated customer then go with Amazon. Amazon never disappoint you.
It's better to search company or store reviews in Google.

My issue In Short:- Croma Executive provide me a tata credit card and I had never used or purchase anything and requested to cancel it but Tatacard charged me Rs3277 unnecessary and damaging my CIBIL score.
