Export PDF - no option to cancel

Hello

I signed up for Export PDF thinking that I could use it with my existing Adobe Reader.  After all, it gives me a wizard to go through what I want to do.

But apparently this isn't the case.

I tried to use the online chat, but the person obviously got bored with me when I asked for a refund and failed to answer.

There dosen't seem to be an option for me to cancel my subscription.  

I'm a bookkeeper and I'm not having my client's bank statements held on the internet, so this isn't going to be any good for me.

Have I lost my money?  I would have thought that there would be a cooling off period, but there is nothing on the account details page except that I have this plan.

Can someone point me in the right direction?

Thank you.
