We used Braintree and during the time they were bought out by PayPal and all th terrible PayPal support was integrated. We could never reach a live person at Braintree again and ended up switching processors.

It's scary to think a processor can't answer a phone call but hold your entire business' money in their hands.

For what it's worth, we recently tried to get a new Braintree account set up (this summer) and ended up in the same situation. After a few months of trying to get in touch with them, a coworker of mine was told that Braintree is being integrated into PayPal and is no longer accepting new customers. We ultimately had no other choice than to switch payment processors.
