I'm starting to think this too. I used to get responses within 3 days. I have an issue with my Black Widow PF and I sent them my first email 3-4 weeks ago and haven't heard back. I've gone back and forth with someone in their support but no one from the returns dept has contacted me. It's really annoying to be told I will be contacted 3x in 3 different emails from a sideshow rep and then not get contacted by the returns dept. I'm gonna email them again if I don't hear from them today(they were supposed to contact me on Fri and of course, that didn't happen).
Same with me, close to 3 weeks waiting on a reply for my Gammorrean Guard.
