Troubleshooting

I am the one who is sorry. I phone  and was told the waiting time was between 1:30 and 2 hours. After waiting 1:28 , it sounds like someone took my call but immediately the line got cut. Extremely disappointed and frustrated. I believe the person who took my gall made an error when answering.

Now to my inquiry. My own tax return was accepted but my wife's was rejected by CRA. No specific reason was given. I tried to go back to see if I made and error but there was not way to go back, absolutely no way. It told be to retry but could only do it 5 times.

I finally mailed the return. Please tell me how I was able to check when I could not backtrack .
