We hope it never comes to that, but if you're in the application process i.e. limits are not sanctioned yet then  discontinue the application to prevent setting up Qik EMI card . 

In case limits are sanctioned , you can contact Tata Capital Customer care at 1860 267 6060 between 9 AM to 8 PM, Monday to Saturday for next steps

Alternatively, you can send an email from your registered ID to customercare@tatacapital.com
