I've used McAfee for a number of years now, and they've always provided exceptional customer service. They're instantly contactable and have resolved all issues I've asked of them. However, for many months the firewall feature and VPN have not worked on my Mac and, despite repeatedly contracting them about this, I've been told that it will be fixed one day. This is unsatisfactory, and I can't pay for internet security where some key features don't work. They clearly do not intend to fix these issues.
