I gave up already. I received my WES evaluation yesterday 12th June, after over a month that WES sent it to me. According to WES, my evaluation was completed on May 8th. I checked the tracking number on the envelope. WES sent it on May 17th from Toronto, it reached Vancouver on May 29th, and to me in Malaysia on June 12th. To those who apply through WES, make sure you order express mail.
Moreover, they only sent me my PhD evaluation. My MSc and BSc evaluations are missing. I emailed them and called them many times to say that I paid for those too, but no reply. I wish I could get a lawyer to sue these a-holes.
