I'm sorry, there is no additional charges at all, and we guarantee our service, so don't worry. Since you do not want remote support, so I need to ask you some more information first before I can provide a solution. Can you please answer my questions below:
1. In your facebook on your computer, click on the tiny triangle near the upper right corner, then click on Settings, then do you see the Username and Email address there?
2. On the cell phone, go to the www.facebook.com website, then sign in your facebook account there, does it work there?
Or if you change your mind, I can easily fix this issue remotely and quickly for you through your computer.
Please let me know your option; we guarantee our service. Please reply at the box below. Thank you.
