Personally I am doing lots of small things to comply less and make things more awkward for the corporations. One of them is to stop paying by direct debit, and insist on paying cash, and refusing to have a plastic account card for anything. This means they no longer have access to my bank account (I have had two mistakes in their favour in the last year), and they don’t have the money up front.
Which means I have the money upfront, my cash flow improves.
People say it costs less to pay by direct debit, but I think this is an illusion. You are getting it apparently cheaper because there is another sort of price to pay. Watch out!
