I agree with SR. Have you seen the charge go through on your card yet? Call your credit card company and ask for the fraud department. Explain that you placed an order over 3 months ago, that you haven't received the product yet, that there has been no replies to multiple emails and their phone goes directly to voicemail which is full. Request that any future charges be denied if it hasn't gone through yet or be reimbursed if they charged your card already.
I've heard a few people talk about their like for theholsterstore.com now. I might have to order something from them sometime to see for myself. The wife and I been more than happy with the MTAC holsters from Comp-Tac.com and they ship out the next day. I also have two of their reinforced contour belts which are very good, quality gun belts.
Let us know if you hear from them or receive the holsters.
