Can someone who knows about twitter help me please???
Here is my problem
Twitter has changed my username and won't let me change it back, every time I go into settings, I change it and it says the changed settings have been saved but they haven't it still stays the same username that I do not want it to be. I know the username is available and I've emailed twitter support but they haven't answered my email. Any ideas of why this could be?
