I was charged for two random purchases:
$16.98 for the Roku Channel App, that I downloaded over ten years ago.
And $14.99 for Roku for WarnerMedia Di..
Neither show up on my account as purchases, but they were billed through a PayPal prepayment agreement that has been active since 2014.
Of course, support can't fix them without knowing what account they came from.. I have one account.
They expect me to find the information fix their mistake.
