Wait a little more longer. I had also the same case and just got my PER today via email.
Please double check lang yun WES request mo, yun sa request mo may "Report Shipping & Tracking" option, make sure that "Citizenship and Immigration Canada - FSWP" is included.
In my case, I lost a valuable more than a month time due to mistake in process by WES. Instead of giving CIC access to my record for the request I did, they sent a copy of my report in my address. And last week, I was able to receive this information via snail mail from CIC - that they still cannot access my record. So I contacted WES about it and they corrected their mistake.
But I am still very happy because it still turned out to be ok, medyo matagal lang nga at very stressful.
Also, i was surprised and it was a relief that I received my PER via email and not via snail mail (similar to other CIC agency applicants).
Just wait a little more ;-) darating din yan.
