The setup is conviluted and not well documented. I had to go to another part of the company to tranfer my domain over and it wasn't listed or documented anywhere. Once the painful setup was complete I took the site live. No sales. None. Time went on and then I ran a card through a transaction and it failed. My processing was terminated, had to get it resubmited. The support is so illiterate the messages are incomprehensible. I spent several days replying that the message is incoherent and asked for someone fluent in engish or grammer to reply the next steps. Someone saw the messages and appologized for the issues. Days later, the site is still not working. I get closed tickets saying the issue has been resolved, but it still doesn't process cards. Not worth the hassle. Here is a copy of the incoherent message as a warning to stay away: I would be more than happy to assist you with your concerns today, i am seeing your account payment account has been terminated due to not processing within day and we can restart your account to start processing but in order to do that do you me to go ahead and see if is possible to restart your payment method for shift4 so you can re-apply/resubmit again your payment method application?
