I recibe txt message of this number and now I have problems with  my girlfriend who think this number is from a person who I know.

Hey ;) I said who's this wanted to chat on y! Messenger.  "Service was bad".

Scam.

Said the same to me when I asked who it was.

A guy called Johnson Bob in facebook, contacted me from this number.  His account seems fake, his pictures too.  

He said he is a contractor and is in Nigeria.  That he was robbed and asked for money.
