I just pre-ordered Cathe's Hardcore Series from CK Sales today. My question is, how good are their customer service? I've sent them two e-mails regarding some inquiries for the past week, but none of them were replied. I've ordered a couple of DVDs from them last week (should be getting them any day now cuz I'm international), but after my e-mail inquiries went unanswered, I'm starting to feel a little uneasy. Can anyone share their experiences about this company? Is it good or bad?
