What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
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.
Unfortunately no. There is no way to recover a deleted submission or deleted incomplete submissions. One possible option is to recover the data from the submission emails you must have received but in your case you have not enabled it in your payment question to send "Pending Payment Email"
You will have to ask your user to submit the form again.
