I don&#x27;t know if someone here had something to do with it, but Twitter support had a sudden change of heart the day after I posted this.<p>They decided to credit my account in full, but still did not explain how this happened to begin with.<p>While I applaud them for doing the right thing, I&#x27;m wary of letting them ever have my payment information again.<p>If someone here was responsible for their change of heart, you have my gratitude.  Regardless, thanks to any who read this.
