I accidentally bought two Acrobat Pro DC due to the internet problem in China, please help me cancel one of it, and return the money.
More, I would like to know how to pause paying the fee? I did not see there is any option there.
You will have to contact Adobe Support directly by phone or chat to resolve this.
