GST TDS under Section 51

A public sector undertaking deducted GST TDS u/s 50 of CGST act in respect of vendors. Due to lock down  at the time of payment of GST TDS, payment could not be made due to GSTIN of vendor being in CANCELLED state as on the date of Payment. Now they are ready to pay the TDS with interest.
 
Query
1. whether they can make payment of GST TDS against cancelled GSTIN of vendors.
2. Whether such credit will appear in their account as and when GSTIN is re activated or will this credit be lost for such vendors.
