What is the toll free number for Norton Security Customer Service to be reimbursed for 2 cancellations?

I have cancelled online twice for an upgrade for Norton Internet Security that was stopped by Norton because I had already had Norton 360 upgrade. I cancelled the same day twice that was a week ago and they have not credited my bank account. Norton 360 did not remove 2 viruses and a spyware. I would get an alert 2 or 3 times a day to reboot and Norton 360 would not remove them at all. It costs me $150 to get my hard drive reformatted and software reloaded with a new virus and spyware protection. I also cancelled the 2 year subscription for Norton 360 to be reimbursed for the remaining amount because of the damage that was done to my computer. I have looked online for a phone number which I can't find. The only thing I found was an online chat support which I have to download and I refuse because of the damage Norton has already done to my computer. Any information you can give will be greatly appreciated. Thank you!
