We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Incomplete payments show you if the payment is successful or not. Sometimes the user can submit the form correctly, However he/she can close the window after redirecting the PayPal page. At that situation, the submission remains as Incomplete.
