I have had 6 messages in the last two days.  They donot leavea message.  How do I block this caller?

I have this number callin me 3 times now.im sick of it.

This number has called at least twice a day for the last five days.  Today was the first time someone was there... "Sylvia" with some company I didn't understand.  Said that they were contacting me because of an online survey I had completed.  I told her I didn't complete an online survey and I wanted my number removed immediately from their calling list.  There was no response and I hung up.

I receved a call from that same number today.. just call your provider and have them block the number from calling or even leaving a message.. if you have the blocker app it will only stop the call from ringing but will still be able to leave a message.

Some one has been calling my cell phone from this number.  They called me March 6th at10:19 a.m. and a gain at 3:01 and again at 6:18p.m.  They also called me  on Thursday March 7th at 10:38 a.m.  On Friday March 8th at 11:33 a.m.  1:52 p.m. 6:18 p.m. 6:40 p.m.
