I gave up with Skype about 12 months ago after I discovered it had been taken over by Microsoft. As a Mac user I don't have a Microsoft account, shock horror! I found my contacts were still there but couldn't access all my credit without a Microsoft account. I managed to open a Microsoft account but they still couldn't sync with my missing credit!!! In order to try and find my credit, I had to answer masses and masses of questions up to a point where I thought I was being seriously scammed! The response was... NOT ENOUGH INFORMATION,! At that point I gave up and lost all my credit! Why bother when there's WhatsApp, Messenger, Face time and plenty of other excellent alternatives? Stuff Microsoft!
