I had applied for the cancellation of my GST registration because I started job and didn't want to carry business. There's no action taken by officers on cancellation, no notice no response nothing.. and I've been filing nilll Returns since then..

Now I am thinking of using GSTIN for issuing bills by showing part time/casual business..

What should I do?
