Thank you for the reply.
I sent email to embassy (good conduct email) two times and no reply. Hence I submitted to IRCC the clarification letter attaching the copy of the emails sent to Embassy. Also informed them that if required, I can send the original received certificate to IRCC, when requested. Waiting for their reply. Hope they will accept the clarification since its genuine and I have attached the emails sent to them along with courier delivery details, copy of demand draft to embassy etc.
Also i wrote to them that I cannot request another Good Conduct certificate as my current certificate is valid until March 2025.
