I need an address to send a complaint letter. I paid for the same service twice last year. I renewed my subscription April, 2016 but they kept sending me messages that my computer was not protected so I bought a subscription again in November. I am old and tend to forget stuff. I did the live chat, Lyzajenn canceled Norton 360 but did not credit my account for the 3 years I paid for. I want to send BBB and the main office a letter regarding this matter.
