Norton – Norton anti virus

I purchased Norton anti virus from Curry's and installed and clearly pushed the button saying no to renewal, about 4 months later i noticed on a credit card statement that I was charged £64.99 for Norton anti virus, trying to get through on there website to complain about this was very difficult so I emailed and explained this had happened. to be honest I have had a lot of personal issue as well as health issues so i completely forgot to chase it up. So yesterday I need to check something on my credit card statement and I see they have done it again taken £64.99 so went on the chat and spoke to someone who said he would refund both just needed the ref numbers I had one from my latest statement but had to locate the other ref number so the guy said soon ss you find it get back the chat and whoever is on will refund it for you, this when some else come on I explained yet again and he said he can't do it I told him to look at the note but he just refused. The annoying thing my Norton I paid £14.99 for and online they are charging £64.99 now weather that has more features I don't know but the £14.99 is sufficient to my needs.
