South Africa Windows Call an Agent (Entering Phone Number)

Tried multiple ways to put my cellphone number so I can get help from Windows. Below number used as example only and is not mine. I've tried the following (+27 is our international code) 012 345 6789 +271 234 56 789 +27 123 456 789 012-345-6789 271 234 5678 I've tried multiple ways really but it doesn't accept the formats. I did search this thread but nothing came up. Any suggestions?
