How to get Support Team to handle a disabled VM due to a suspicious activity

Been receiving emails in my personal email not related nor connected to my VM account demanding payment but no invoice is issued in my VM account. I engaged Microsoft on this. But early today as I was working on my VM it was remotely stopped with a message that there was a suspicious activity. Getting to Support Team to attend to my issue is too tedious; submitted request provided response not related to the issue; Support virtual assistant via chat nor phone responses were also off the mark - none related to this issue. How best can I get this resolved? Thanks,
