ive had this happen to me also. someone used my number saying that i was moving and i had to get rid of my prize winning poodles. i had ol ladies blowin my shit up all day and night asking where they could take all of these poodles. i flagged the ad and nothing happened. so i flagged it every day for a week and it finnaly went away. i then changed my number and only my family and close friends know it now.
