I had a similar experience with Sainsbury’s Bank in the U.K. Called me out of the blue after a failed transaction, I refused to give them the info they wanted and so they locked my account. Unlocking needed me to send them physical info that would have cost me. Easy to sign up for an alternative. Lost a customer after 15 years. Well done Sainsbury’s Bank.
