Between '06 and '19 I was a client of bank that proudly bear the title of "pioneer of online banking" here and tbh, they actually were. You won't met anybody in Poland who wouldn't have contact with that brand one way or another. I opted-out for all marketing purposes once they allowed to do so but yet, I was getting random calls from bank and 3rd parties. One day I called them because I had login issues on Windows Phone. I did mention to consultant that I was getting these calls and in return lady hit me with quite a revelation: they had a single opt-out that was only available if you called them.
