Unreliable
I've just had a large transfer from a customer bounced. All the details on the transfer were correct. Wise customer service say they will investigate and get back within 1-2 days. Meanwhile I am out of pocket $10,000 and my customer has been charged $15 for the bounce.  It's not the first time I've had slow/problematic transfers. If you can't rely on a financial provider why would you use them?
