I too have fallen foul of the card payment system, which I did not set up on my invoices2go account or want to offer my customers. Unknowing to me Stripe attached the payment system to my last invoice to a customer. Sadly my customer paid on a card and not by bank transfer as I had requested. Don't ask me how as the account wasn't set up to take card payments Stripe took the payment and now demanding that I complete a form of personal details before they will release my money minus a commission for handling it. Even though 10 days ago Invoices2go instructed me how to send the payment back to my customers card, It now seems I still have to sign up with Stripe before I can get my money. I am one very uphappy, frustrated and angry customer who will not be using Invoices2go ever again.
