My Monzo credit score is penalised due to not being registered to vote, but I have been registered for years?? Can anyone help?
Is the address the credit agency have correct? Is it exactly the same as the one Monzo have?
You need to speak to Credit Karma, it’s nothing to do with Monzo.
More specifically you have to raise a dispute with TransUnion. The info on how to do it is here: Disputes FAQ
