Downhill fast, and stole nearly $400 from me – Flint - Accept Cards, No Dongles. Invoicing. Review

I've used Flint for about three years without incident, until last week when two transactions went terribly wrong. The amount put into my bank account was not even close to the transaction amount, and when I try to contact customer support, to my surprise there was none! All I got work email responses from what could only be a computer-generated support. Don't try calling them, because the number will not work. Two transactions in a row, and nearly $400 in unaccounted money, and I am taking a walk. I demanded that they cancel my account immediately, and I would think twice before you sign-on. Terrible!
