planes y facturas duplicadas

If you have an individual plan, you will have needed to create 2 different Adobe IDs, as you can't take the same plan twice on one account. If you are still in the 14-day range, you should cancel the newest plan. (https://account.adobe.com/plans) If you are past that 14 days, you should contact Adobe customer service. Adobe customer care can be contacted by beginning a secure chat session at https://helpx.adobe.com/contact.html?rghtup=autoOpen. Pop-up blockers need to be disabled! If the chat window fails to open, or is non-responsive, use a different device to start the interaction.
