i received a call from this number. I called back and found that is not in Service!!

I received this number calling me at 11:30 p.m.

when I went to call it the next day...it said that number has been disconnected....

Now I don't believe anyone will call to tell me why this happened......just wanted to report it

I get a call from this number every day. It is a fax calling

Have got multiples calls on my office phone from this number, which is obviously a fax. How do I make it stop besides checking call display and hanging up.

Received a call from this number and it was a friend calling using skype

I am at work, I cannot be accepting calls while at work, I did not answer it, I called it back on my break and it was " the number is not in service "
this is really bothering me. If it was a fax calling, wouldn't it have handshake or fax sounds. ?
