No response so far. Have pinged them again today.
Sorted this out... by myself, and also received a call from Zerodha this morning.
The settlement of 40 LiquidBees was 37.343 units from CDSL (Zerodha DP) and 2.657 units from NSDL (IL&FS DP). There was no SMS from NSDL, as used to happen earlier, to alert one to this possibility. The resulting balance quantity in IL&FS was 0 as on 2019.01.10.
Currently, a dividend quantity of 0.002 has been credited to IL&FS on 2019.01.29, so that remains to be sorted out.
