I filled my return on 2nd April, but never received any acknowledgement/ communication from CRA. Unable to refile too. Pls help.

Did you get a NETFILE confirmation number? If you didn't, then your return wasn't filed.

Thanks for response. I did get Netfile confirmation number when I filed.

Then you will need to contact the CRA to ask why you haven't gotten your NOA yet. 

If you are in Canada or the United States, you can call the CRA at 1-800-959-8281. If you are elsewhere, you can call 613-940-8495. This page has more ways to contact the CRA: Contact the Canada Revenue Agency
