It can be really demoralizing when the system isn’t working properly and support isn’t responding. Unfortunately, there is no easy answer for you here. You will still have to invest time and double check everything that is related to funds. But there are a few ideas that you might consider. First, it’s always a good thing to check if there are any technical problems with the payment system, like issues with the bank or card. Secondly, you might want to try making the donation through another method, if the platform allows that. You can even build your own website and use pythonrpa.org Python bot to count all your users and fill in all the necessary forms you might need. Additionally I recommend you to chat with developers about additional, more complex tasks you can get help with.
