When I placed my order for the instrument 1, i used Amazon pay. it said transaction could not be processed so I checked my bank account and saw that the transaction did process, yet I didn't recieve a confirmation email. I talked to Amazon and they confirmed that a transaction was made, so it seems a glitch occurred on Artiphon's end. The funny thing is inwas supposed to be charged 307, but i was only charged 304, leaving my account at zero. Could it be that instead of denying the transaction because i was slightly short, the system let it go through, but because i didn't have enough it got confused and scrrewed something up? Ireally wish Artiphon had an option to call for support instead of leaving support tickets because losing $300 kind of a big deal, and id really like to know if I actually bought the dang thing or not. If anyone has any light they can shed on this, I'd appreciate it.
