Sorry to hear about your experience.
As you said that after exporting the pdf to word the data doesn't copy correctly, so I assume you are referring to one specific pdf file for which data doesn't reflect in correct format after converting the pdf to word?
If this is the case, then you may try converting a different pdf to word and see if the result is same?
To perform the correct steps for conversion, you may refer to the steps suggested below-
1- Export PDF is an online service that you can use online via: https://cloud.acrobat.com/exportpdf
2- You can also use the services through free desktop version of Adobe Acrobat Reader DC: Adobe Acrobat Reader DC Install for all versions
3- “Sign In” using the email (Adobe ID) under which you have subscription registered.
4- For detailed description of how to use the Export PDF service, you may refer to- Using Adobe Export PDF
Also, the quality of converted document depends on the quality of the PDF file you start with. You may read this article for detailed description- Text is garbled in a converted file | Adobe Export PDF
If you are still not satisfied with the service and willing to cancel it then you may refer to the help document here and follow the instruction for cancellation-
I’ve tried doing a couple of those things but still having no luck.
I downloaded this application for a specific purpose and unfortunately it doesn’t work for the file I need exported.
As the service doesn’t work I would like to request a refund and I will be canceling the subscription.
Please get back to me with the decision to refund me or not. If you aren’t able to refund me I would ask that the issue is escalated to your management.
