By being consistent. Different help agents say one thing and it is not true or another staff states differently.

Please alert me when I do something my plan doesn't support.

I was told I could Edit with the "PDF Pack"
I was told and read I could combine files under the same plan. I now have PDF Pre mium plan as your staff stated it was the way I could do things as noted above.
I cannot afford to pay any more for signatures and management of the PDF's. I need a thorough explanation of what I can do with this plan and an alert if I am outside of what I purchased. Thank-you.
