That's cute. Your records are yours. Barring some agreement to the contrary, I have no right to mess with them or inspect them, even if they contain information about me.

Like most of the GDPR "Right to be forgotten" is not an absolute right. As you'll quickly discover when you insist that the bank needs to "forget" that you owe them a lot of money, there are plenty of legitimate reasons they can decline to "forget" you despite your invocation of a "right".
