Cancelling my norton

Hi,

 

today I received my credit cards bill and I just saw that Norton charged me 91$ without asking me because it was automatically selected. I NEVER ASKED FOR THIS. I want Norton out of my life now, but I cant cancel my subscription because the chat does not work, its too late to phone you guys, and my 60 days is going to be complete soon so I really need this subscription canceled.

 

What can I do ?
