Unauthorized billing

Avast, im removing all your relsted software and products from my pc and android device. I just recently billed for this cleanup product i did not want or use yet you managed to somehow procure my credit card number from i assume the purchase of your VPN or securline product over a year ago.

I am retired military living on a fixed income and the $23.88 you charged me from my account is that much food i will not be able to eat until either you or my bank process in this dispute process.

Thank you
