I successfully migrated from Service Tax to GST but after few days while login it shows that your RC under cancellation. After conversation with GST helpdesk they asked me for fresh new registration and successfully I got registered with GST but with new GSTN No. in September 2017. GSTN no. earlier issued to me has already given for sale n purchase. Now what to do ??
