Can not cancel premium free trial

I was going to see if I could contact a support line or a live chat but I guess i have to pay to have that privilege. I just got avast and got a free trial for the security and vpn but neither work, anytime i try to use them they tell me i need to pay, isn’t the whole point of a free trial for me to use the program without having to pay? Would just like to cancel my security trial, I already cancelled my vpn one but for some odd reason i can’t deactivate the security one.
