ChatGPT Users - Top-Off Credits For Chats

Has anyone used the topoff yet? I'm writing a story and when I was at 25%, I switched to fast from expert thinking that would help. But fast sucks and frequently sends you old garbage instead of following the prompt. So when I found out my limit is gone and doesn't renew until the 9th...! Has anyone tried a top off? I see a lot for videos but I don't use videos or pics right now. I only do chats and I can't find anything on it.
