I'm about to lose my shit at Mcafee...
I've been on an account cleanup spree recently and deleted over 100 inactive and old accounts all over the web. The last hold out before it's done? Mcafee.
After back and forth with their support, they insist I have a product with them, even though I don't really. Turns out one of the laptops I bought 12 years ago came with a subscription to one of their plans. They cannot delete my account until I remove this plan.
