You guys make it painful to cancel. Honestly not happy whatsoever with the service. Cancel cancel cancel subcription.
First, I’m an Avast user and not an Avast Team member.
You don’t say what product this is that you want to cancel, given you have posted in the General sub-forum doesn’t shorten the odds.
You don’t say what you tried or any potholes you bumped into, so it is difficult to offer advice that you may not have tried already.
