I sent you an email at 1442EDT yesterday July 1, 2103, regarding a billing question, as I wanted to start my subscription to activate my store.
I got what was obviously an autoresponder telling me that you had received the message, and hinting at a response within 1 business day. It is now as, I write this, more than 26 hours since I sent the email and got your autoresponder. Surely 26 hours is longer than 1 business day, no?
I finally broke down and used the phone, only to be put on hold, then told to leave a message, even though the voicemail system itself clearly informed me of live working hours that close clearly more than 2 hours after the time of my call.
You have already given me so much free development time and server resources, much better than any other shopping cart extant that I have worked with, but if this is how you respond to billing questions, which will putatively put money in your pockets, I must say that it inspires little confidence in your ability to deal with payment, heck, even straight-out customer issues, for that matter.
I am deeply impressed, and highly disappointed!
