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.
I just open pdfs in the (firefox) browser. Does most of what I need.
My company pays for it so we can edit pdf forms.
Sadly not many capable tools for that exist. Open for suggestions (Windows) though
