I had the same experience with Khoalty, sent repeated emails with no response...only to eventually find a response in my junk mail folder. I didn't even think to look in there, just a thought. That aside, I found their customer service to be awful and rude, and will never buy from them again. Umnitza FTW! They answer their phones, they're friendly and will negotiate on cost with you if you're buying a few items.
