Just tried Purse to buy on Amazon with bitcoin. Great idea, poor system, hours of waiting for support and non-skilled staff who answer about orange when you ask about apples, although this last thing is pretty much everywhere now. Worst of all, no option to close an account, not even an entry about it in the help. You have to contact support! I can't imagine they handle well the data privacy.
Then when you (the customer) ask why there is no option nor result in the help about closing an account, they block you (the customer). It's a big no!
