If they're this useless when you're trying to give them money, how do you think they're going to perform when you need something that costs them money e.g. customer support?
You're right. And Paypal's business support hotline, which I am now intimately familiar with, is already very bad and their backend merchant portal is a bad joke - I found dozens of bugs, untranslated strings, weird workflows...amazing what you can get away with when you're a monopoly :(
