Chandan,
You should get the reply to your email anytime now as it was sent on 27th Nov. Generally CIC takes 30 working days (generally 50-55 calendar days) to revert to queries. The email should address your issues. In case you do not get the email reply from CIC, you can call the CIC call centre.
CIC call centre will not give you status of application, but you can try to get UCI from them. Call on 1-613-944-4000 and use options 111 113. Then don't input any data when asked for application number thrice. Your call will be then transferred to a call centre agent. Tell them of your problem and ask them for the UCI number. If lucky, and if the agent is cooperative, you might get the UCI. Use this UCI to check ECAS status on the following link https://services3.cic.gc.ca/ecas/ECAS.jsp. In case ECAS is live, your app has been charged and date of application receipt at CIC can be known.
If both these things fail, write a fresh email to CIC again and wait for CIC revert.
