Yes, I did call. Actually, I started doing a search of what people were wicking or any problems and found a thread where people were asking for must-haves from WSP and someone said to get this, but thatthey had had a bad batch recently that was replaced. I so I called and said that I beleive I was having a problem with it and that the tester I had had with it worked great was there a bad batch I wasn't aware of. They said they hadn't heard anything from anyone and that it must be something I'm doing. That's when I gave up. But then this past Christmas I thought if there had been an issue, it probably was resolved by that time and bought another pound, same problem. I've given up since then,
