What if . . . your son received threating phone calls?

WHAT IF? . . . my son received a threating phone call on his cell phone last night. I will not go into the detail but I am hoping mad (o.k. let me have you all rolling on the floor at this point since I cannot walk right now and am laying in bed typing this hopping is a distant dream:)). I am a mother bear, Dr. Laura says "I am my kids mom", no I do not think that describes with enough GUSTO, I AM A MOTHER BEAR, I will stand 9 feet tall, I will take my big paw and claw you to the ground, I will stomp and sniff, and I will stare you down until you leave! Don't mess with my genetic stuff. (of adopted stuff).
I digress now back to the phone call, this came late in the evening and this person was not intimidated by an adult, this person knew he was not at home and knew he had older siblings. Supposing this was you? What if this was you? What would you do? Well let me tell you what will not do you any good. One whomever your cell phone carrier is cannot help you with a blocked call phone number. It does not matter how nice, or how grumpy you are. I am not sure how this is possible because they are the ones whom issue the number and track the number. They are also the ones who promptly want their money the day it is due.
Next option try to call the police department and stress the severity of the situation. Now I understand that in Police world this is a blip on there radar screen, in my world, it is my world. I am not sure if the words that were coming out of my mouth I AM AT HOME ALONE AND CANNOT WALK. Went into his ears, or, if the words, MY SON IS AUTISTIC, went into his ears, or if the words, HE WAS NOT INTIMIDATED BY AN ADULT, went into his ears? He simply said that it MUST be a 'friend' that is pranking him? A friend, really?
Well let me re-cap if you receive a blocked call - DON'T ANSWER.
Second choice - The police department took a "report"
Third choice - If the harassment continues the cell phone company can put something on his phone that tracks the numbers? (apparently only the policeman understands this because the cell phone company doesn't).
I hope that this saves you the running around that I have done.
The answer DON'T ANSWER.
Happy Friday, do something that takes your breath away this weekend!
I get to go pick up my daughters prom dress - woo-hoo- she drives me, she pushes me in my wheel chair, and well then she puts me into bed, go girl!
