Cancellation of cop

Hello,

I am a member of ICAI having membership no 144628, I have given manual hand written request for cancellation of my Certificate of Practice as on 27th Feb 2018, but till today I haven't received any communication from ICAI regarding the same.

Please help me for any communication letter issued by ICAI for surrender of COP with effect from 28th Feb, 2018 along with cancellation of my firm name from records.

I need this communication for future reference as I am currently employed in organization as an employee.

I hope a quick and positive reply from the expert.
