Scam. They double charge and nothing they offer is free.
They're definitely a scam. While the product is real, it's surrounded by shady business practices. They're very misleading and clearly don't actually care about customers. They're only interesting in making money.
They claim to be legitimate, but from my experience they're more concerning about taking money than providing a value adding service.
Legit in the sense that it probably has a profit and loss and a website. Beyond that it is an immoral company and very much into scamming.
This service is run by bait and switch scammers. They will squeeze you for every penny they can.
