My question involves a traffic citation from the state of: California

I recieved a ticket last month and there was no amount due on the ticket. I was to recieve the amount due in the mail several weeks later. I recieved in the mail the amount due, however, my last name was mispelled on this document. I went to look up my case online and had to look it up under my mispelled last name. So the case is under a last name that isn't mine. On the original ticket, my last name was spelled correctly. My question is do I have to pay this cause the case is under someone else's last name? Should I call the office and say no one of that name lives here? What are my options and can I get away with not paying it? Thanks in advance.
