I tried to buy the iPhone 5s unlocked today with my debit card but every time I click place order, I get "Your payment authorization failed. Please verify your information and try again, or try another payment method". I know my billing address and bank account is in good standing because I just used it yesterday. The only explanation I can think of is that my bank, Chase, thinks it is a fraudulent purchase because 650 is very out of the ordinary compared to my normal spending habits but I have spent close to 1000 many times through PayPal so that doesn't really check out. Does anyone have experience with this error and how to proceed?
