Acrobat Pro 2020 Standalone Refund

Adobe support often send people to the forums, saying support is there. Sadly, this is a lie to get people off the line. They have been told not to, clearly there are strong motivators for them to do this.

It's not clear whether you can get a refund, since you haven't found anything wrong with the product, you just didn't check what you were buying. Same as if you purchased a car that wouldn't fit in your driveway. It depends on the refund policy of whoever directly sold it to you (not Adobe, unless they sold it to you).

You should contact Adobe directly for help with this issue:
Chat support: https://helpx.adobe.com/contact.html?rghtup=autoOpen
(type "Agent" to chat with a real person)
Phone support: https://helpx.adobe.com/contact/phone.html
There's no email support.

Beware of people contacting you via the forums' messaging system pretending to work for Adobe! Only those with an "Adobe Employee" tag under their name are legit. Also, Adobe will never offer to contact you via Skype, or use an email account that's not under the adobe.com domain...
