Refund norton 360

Hi

Downloaded a new version of Norton 360 Premium which I purchased when purchasing my new laptop.

I registered and downloaded it yesterday. 

I was asked to update banking details which I did.

What has happened the download did not upgrade my Norton and you charged me $300.97.

So the $548 registration has not taken effect and you have charged me and additional amount.

If you could please refund the $300.97 and advise how I can activate the newly downloaded version.

Thanks
