I accidentally topped my $$ account. How do I request the refund?

 
Hi. Please would anyone share a link where I can create the request to get the refund for the accidentally topping my account? 
I read a bunch of answers and found relevant buttons that can't be clicked on them. 
In sum, I have money in my account that I deposited. I don't plan to use them and I'd like to get them back to my card. 
How do I do that? 
 
You can't withdraw unearned funds. Contact the service desk. Bottom of every page is Contacts and requests.
