I have not install the 2017 licence on my pc I don't know the number because I have had some problem whith my old mail (rita.sicilia@gmail.com - this account  was cloned and I have delated it and  I have created a new mail)
my last invoice with 2016's licence, but I haven't recived the invoice of 2017 year and I hanen't the new number's license because I have closed the old mail; all my payment whit my old credit card ( for the some problem I have change my credit card)
 
I was taken from my 50 euro card on January 17, 2017 for the renewal I NEED required. Since I no longer have AVG in my PC, now I would like to cancel my license, I have changed my mail that I had in the first year since I paid my first license in 2015. My current mail is ramarro.z888 @ Gmail.com. Please I want to cancel the license tell me how I can do thanks!
