Here's another dark pattern: OVO energy in the UK. They will direct debit you, and take your money. Over time, you build up a large credit balance because you don't use the gas and electricity that much. So you go on their webpage, and there's a refund section. It says you need a direct debit to get the refund. You click through to get the refund. It says you need to call them. You call them. Guy says he needs a photo of the meter, reasonable enough. But also he says he's limited in how much he can refund. You'll have to call again tomorrow. You send the email with the photos. You get back an email. They can refund you, but it's a cheque. You have to go to the bank, in a week when the cheque actually arrives, to get your refund. They can't just pay you with the bank account details you already gave them.
