I sign on to my account on Xbox.com and try to chat with Microsoft support. But I keep getting a error, It's says at the top of the Chat with Microsoft page "Invalid data. Please check your information" and then under first name it says "Please enter a valid first name". I think it may be an issue with my first name is says "Phillip [Adam]" I think it's the brackets that are giving me an issue. I have tried to change my name on my Microsoft account but it doesn't reflect on my Xbox.com account.
I would greatly appreciate any help,
