Banks selling/providing our individual transactions' data (without consent)?

I came across this post on Linkedin where a group (Nova Credit) claims that they have access to our bank transactions data to measure our cash flow. I can assure everyone I never gave my bank permission to give this data away, even to those it will claim to be 'service providers' if challenged.
