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.
I confirmed that you have reached your limits for the "Payment Submissions", because on Free plan, you have only 10 payment submission right per month. If you are interested in upgrading your plan, we have an ongoing discount "Holiday Sale" currently, so you can find reasonable prices on the Pricing Page.
If you need any other help, please let us know.
