My wife and I feel the same. Completely heart broken. Our application arrived on the 30th (would have been the 29th if not for UPS screwing up). Our NOC was cold too , 4214, so we never imagined this would happen.
We have spent the last 8 months thinking about nothing else but our application and our new life in Canada. Every day checking our ECA status with ICAS ( for 18 weeks!!) , then once our application was delivered we have made plans and talked about nothing else. The last few weeks I was monitoring the forums and charging dates, so I have been checking our credit card and calling them every day to make sure no transactions have been declined.
Then today came...and everything we have felt and been through has come to a head...an end.
There are no words to describe how we feel. We have a plan B, and it doesn't involve Canada, it actually involves us staying in the UK. We can only assume everything happens for a reason. Right now this isn't much comfort, but please think of this before you get too disheartened.
Good luck to you for the future....
