Not mine but this is actually what I did too.
I said I plan to charge back on my credit card. They threatened that if I did that, they can’t promise my account wouldnt be flagged.
I said “bet” and they removed the cancellation fee and cancelled the service.
If you have a business like a law firm where it is VERY IMPORTANT that a PDF has certain qualities, free tools for PDF creation can be a big gamble, especially if you have to open a PDF that someone else has created and do changes to it. And the cost is pretty trivial compared to the cost of messing up.
