Yeah, I had a meh experience with a company I won some juice from on reddit for the same reasons. I didn't get response from emails for a week or two, forget how long. I was getting ready to flame them when I finally got a response and traded a few emails back and forth on one day.
I figured everything was resolved with my request, waited 2 weeks without word or items, emailed, no response.
I didn't want to keep nagging about free crap, waited another week, emailed one more time before flaming, got a reply back that the person had been out sick or something. Finally got my juice, though it was still missing something I'd won. Since the juice was what I mainly wanted, and again this was all free, I'll just leave it at that, no need to bother with it. I won't name them since hey, they gave me free stuff, but I'd certainly never purchase anything from them given my experience. I would have called them out on Reddit though if they ended up just totally ignoring me.
