I had the same problem. I was mugged in Paris and the credit cards I had linked to Skype, blocked and replaced. Took FOREVER to get the new numbers on......OK, exaggeration, only 4 hours!
Skype has been on all my devices for years and saved me lots on calls to landlines, in addition to the free calls between devices. But it has certainly suffered since Microsoft.......
Facetime is normally clearer and better video, better audio.
It seems you are confusing FaceTime (Apple´s iPhone video conferencing app) and Facebook.
They have nothing to do with each other.....
