Hello...I have applied for cancellation one week back and I got a mail that my GST is cancelled. But Today I received a email "Notice to return defaulters u/s 46 for not filing GSTR-3B" for Nov month.  The problem is I din't open Bank account in the name of the company and also no Net banking . so How to pay the amount? Can anyone help me to clear those, will pay professional charges . Kindly let me know
