A Twitter spat has percolated between Stripe and Mint over Mint’s questionable account cancellation process.

The story goes like this: Recently, Stripe’s founder, Patrick Collison, tried to cancel his Mint account. As he went through the cancellation process, he encountered this customer service message:

Account Closure

If you would like to cancel your subscription, please call our on-call protection specialist at 1.866.373.7830. For security reasons we cannot process any cancellation requests via email.

If this was most any Mint customer, the notice would have engendered a grumble (or two), but the customer in question is Collison, one of the founders of Stripe, who knows something about account security. And this protocol did not sit well with him.

Yesterday, Collison called out Mint, which is owned by Intuit, on Twitter for what he believes is a dubious practice. Collison called it “skeevy dishonesty” and “disappointing.” “Mint: secure enough to store your financial data, but not secure enough to process a billing cancellation request,” he wrote on Twitter.

The post led to a handful of comments from others on Twitter, including some from consumers who said they, too, were dissatisfied with Mint’s account-closure practices.

We asked Collison whether Mint responded to his tweets, and he said the company had not. Perhaps a Mint exec will call Collison today?
