i need to talk to a support person

Hi have you switched regions lately? Or said you're somewhere you aren't? Is it a prepaid card from another region ?

Could you please explain what you mean by "set up my new game card"?

You can talk to a support person by going to https://support.xbox.com/contact-us, and then when you're at step 2, depending on the time of the day, you will see an option
of "No thanks" when asked about Virtual Agent. Click on it and on next step choose the option to chat, or call back.

My xbox one s say i have gold. But i can't play online game

Your probably best going here and selecting the music and video option;
support.xbox.com/.../contact-us

Xbox Music/Zune support hasn't had a phone line in at least a year, probably longer. They do primarily chat support in order to push links and the like to your computer.
