Not sure what you are talking about. This is a forum dealing with issues around Windows Server 2016 Technical Preview, and you mention Windows 10.
From whom did you receive a service call? What errors and warnings are being displayed? What 'staff from Windows 10' are you talking about? What phone numbers are blocked?
If you are wondering if Microsoft automatically calls people who are seeing errors on their systems, the answer is 'NO'. You will need to provide more information if anyone is to try to assist you. Or, you could give Microsoft support a call.
