Linked Accounts found when trying to connect XBox account

I am having trouble reaching them. I was on chat hold for over 8 hours until they opened the chat at 4 AM this morning (when I was asleep, the request went out around 7 PM yesterday. Since I didn't answer, they closed the chat. Since then, I have been watching the chat request like a hawk and none of their chats come through. I only receive emails saying to rate my chat experience, at which time when I look at the case log I see they tried to chat with me multiple times throughout the day, yet my screen consistently said I was still waiting for chat, 99+. I have provided my email and phone number in the chat requests praying someone would use something other than the chat to reach me. I am over 24 hours since requesting the chat and have gotten zero support. This is beyond terrible support.
