They sent me 2 of the wrong size underwear & claimed that I ordered the wrong size. They offered a 20% discount on my next purchase but then refused to honor the 20% discount because I had purchased promotional items?!? I think it's very odd that when you get your confirmation email the sizes aren't listed, but then they are listed later on when they tell you your order has shipped? Obviously whomever picked more order screwed up, or if I did order the one size, didn't think to flag the order & contact me to confirm sizing before shipping the order. Very poor customer services. I understand you can't return underwear, (even if the package wasn't opened) but seriously, train your warehouse staff better. If 2 pairs are a different size then the rest of the order something is obviously wrong.
