Yeah, on Facebook and Twitter they just dismissed me with a generic response.
On the website I also submitted via the contact form, the first one got a "we are forwarding your email to the relevant department" response about a week after submitting, then nothing after. The second time I didn't get a response. But a week or two after the second submission I got an update in my WES account that my evaluation is under review.
I think maaaaybe harassing them via contact form is a little bit more effective than Facebook/Twitter? It's hard to say since they didn't respond to me via email either, but I've seen people on this forum say they got updates a day or two after writing to them.
12 May is really long. My updates were 24 May and 31 May "we are receiving your documents", then nothing until 30 June, saying my report is due 22 July. If you haven't had an update since 12 May that's almost 2 months!!! They are incredibly unpredictable.
