On the expiry of 20 days from the submission of application for GST Registration when no response is received I have applied again for GST.

Meanwhile the previous application is approved & we have granted GST Registration & today I also received email confirming another approval for second application.

Q1 What can i do to cancel one Registration??
Q2 I haven't login with second gst credentials, so if I ignore & don't login in, will it be canceled automatically or I have to initiate for cancelation??

Thanks in advance
