Windows 10: Receive an unknown billing

How can I deal with an unknown billing

:)

 

Windows Phone 10 ERROR receiving a call from an 'Unknown number'

Windows Phone 10 , version 1703 build 10.0.15063.540

Lumia 950 dual SIM

I apologize my English writer !

After last update ...

When I received a call from a private number , Unknown , all numbers and contacts in a list of received / called in a historic phone disappears and, the total number of calls is stamped in Unknown number.

If a erase the Unknown of a historic list, I loose the historic of all calls

The news calls after Unknown are showing normal and do not erase when I erase Unknown

Thank you in advance for Help !
