I'm sorry but you cannot directly contact the recovery team by phone or chat. They work solely behind the recovery form and process. If you have all of them still opens, you need to wait for them to resolve or close automatically and then make a new one.
You might also be able to "bump" or escalate the tickets you already have instead. Do you still have access to the previously received confirmations for the three support tickets you opened? Check on the emails, there should be a link to "View the request" or "Check status."
If you can't process through there or can't find it, you can try to reply to the ticket email thread directly. It's normally from a "no-reply" address, but it's still worth trying. Clearly explain that you need a follow up on your ticket as it has been over two weeks since you opened.
