Grammarly posted unauthorized charges, duplicate charges, and recurring charges on my credit card account, long after I terminated their services, and long after they promised to stop posting charges on my credit card.
The website bills itself as a “free” service, but is very deceptive and misleading, and it’s very easy to end up being charged without intending that.
When you dispute the charges with your credit card issuer, they fight the billing dispute tooth and nail, and even lie about what you, and they, said and did.
