Update: 29th August 12:18 PM Files are getting processed slower than usual, this could be in light of many brokers initiating such requests. 60% of the shares have been transferred back. Once the other 40% is done, we’ll setup the pledge. Expected time of receiving email from CDSL for pledge: 2:00 pm. You will still have time until 8.00 pm to authorize pledge.
