Extremely difficult and frustrating. I waited well over an hour, on more than one occasion, only to be either misinformed, or told they had no answers. This is more understandable, however, than their inability to properly inventory their own products. Furthermore, final representative I spoke with (the one that cancelled my order) was very nasty when he told me "HE can't cancel ANYTHING. He'll let the warehouse know." Yeah, real comforting, especially considering the other reviews I've seen regarding their not cancelling orders. Not to mention his obviously irritated tone. We shall see!
