HI I WANT TO KNOW WHO USE THIS PHONE NUMBER BECAUSE I HAVE MESSAGES FROM THIS NUMBER  PLEASE CAN YOU HELP ME

There isn't anyone here who can help you find out who this number belongs to. You haven't specified why you are asking. What do the messages say? How many times have they called? These are things that might be helpful to other people who get a call from this number. So far, you are the first to report on it.

Another thing: Please don't type in ALL CAPS. That's considered shouting and rude.
