Unfortunately, I mistyped in my previous reply and the correct option would be 4. Luckily, it was not a big deal, because the both lines are assigned to system administrators. They could be busy when you chose the option 4, however, if you would leave a message, you would be called back as soon as possible.
As for the dedicated chat, it was temporary shut down so that staff could concentrate on two primary support areas: helpdesk and calls. However, we hope to enable it back at some point in the future.
Please advise, if you have any further questions or concerns.
