I applied with WES for my ECA on Dec. 13, 2016. Documents were all sent and the last one was sent on Jan 11, they mentioned online that documents will be received 3 days so January 17 because of the weekend. I finally received my ECA on March 1 but they made a mistake with the name of one school so it is once again under review :'(
I found the best way to reach them, aside from email which took them 3 days to respond, would be on twitter @WESCanada. I posted my complaint for 3 days, the twitter team sent me a direct message, gave them my reference and then a few days after I received my ECA---finally. They take forever and are not very responsive especially with their emails and once again i have to wait until one change is done. Thank god i did it way ahead but i missed 3 EE draws because of them.
