You better hope you have no issues with them or you will be SOL. They purposely leave no contact info for a reason. There is no contact phone number and their emails are all fake. They never even bother checking their email addresses or they would realize that their inboxes are full and cannot accept new messages. If you try Googling any of their addresses, non of them are real! I live in San Francisco and there is no such thing as PMB 136.
If you are dumb enough to purchase a Case from them, do it through eBay or PayPal where you will have buyer protection if they try to rip you off.
