Sounds like you have something on your PC that preventing you to access support live chat.

Probably a plugin on the browser.

Suggest downloading a new browser like Firefox or Chrome or Safari and use that to access chat instead of what ever browser you are having issue with.

Chat is always up and running 24x7

OR Try a PC at work or at a library or at a friends or relatives house and you will see it works and is isolated to your PC's.

We are sorry that we don't offer email or phone support.
