calling from this # nonstop since 7am

I got call from this number atleast 6 times and 3 times when i picked up there was some sound.

Just got a call with no message.

I just recieved a mssg from this number 310-825-4321. The mssg. " Hi, yeah, this is Iris @ Dr. Alejos office at UCLA. This is Lauren Alejandos parents, please call  me 310-825-5764. Please call me. Thank you. Bye." VERY, VERY SUSPECIOUS!!!! 1st she states she's calling from Dr. Alejos office, then she states she's Lauren Alejandros parents..... hummm! I can also tell from her tone of voice she was reading the number to call back. I surely will not call these people back.

I SAY IN LOVE ------ GET A HONEST JOB LADY!!!! SHAME ON YOU!!!

Getting this type of calls everyday, and doesn't stops. God knows what to do. They are just motherf**kers....Does anyone knows how we can stop this?? May be are gathering our information to do some sort of scammmmmm???? Be-aware.
