Mail.com lists its services and braggs about it. Supposedly it is a frees service where you have to give your personal information and cell number. Problem is, the email doesn't work and one can't receive emails or send.
They offer for you to upgrade to a 'premium' and if you used it as I have for a registration of a software product, you are out of luck because you can't recover either. A real scam promising free email and delivering nothing.
