KARVY are always late in finalizing/publishing the allotment status. I doubt there are few internal negotiations going on before the final allotment results are out.
Finalisation of Basis of Allotment - Aug 5, 2019 Banks have already started refund of the amounts/unblocking of LIEN amount (as publishes on 6th Aug) however allotment is still not out. SEBI should take a note of this
