Charged when shouldn't be ..

Hi I tried your DC software, didn't like it (kept messing up documents), canceled and yet I have been charged....

How can I get a refund for the charge I didn't want going out?

The "real help from real people" isn't real people, it's help topics...

Which is not at all helpful for me, especially as I'm dyslexic!

P.s it's a bit of a dirty trick taking bank details before trial, hoping people like me will have difficulty cancelling
