Auto renewal

My old computer died a couple of years ago and now I have a new one. Unfortunately my old Norton was auto renewed and therefore I still get charged for it even though I can't use it!

Any ideas of how I can resolved this?  I have Mcafee on my new one which is coming to an end soon so I am quite happy to use my old Norton (which I have paid for) and swap it over to this one.

I have a feeling that my old contact details were through an old defunct email address hence no communication from Norton, it just appears on my banks statement each year!
