Been using them about 4 years. Credit card fraud has increased dramatically since switching to them.I would love to tell you why, but repeated requests to support for help in plugging whatever weakness the thieves are exploiting have yielded no help. After a recent attack that cost me over $2500 in losses, I received a demand from Braintree to submit bank statements to them to prove that I could afford these loses in the future. Seriously? No help - just a demand to prove I could afford to continue to be ripped off.Sorry, Braintree. You're right. I cannot afford you. I'm done.
