they call all the time and will not remove me from their list

I get calls from this number daily, I have tried to call back but the number will not go through.  Based on other posts I'm guerssing it's an education telemarketer as I have been appling online for jobs and do get several calls from telemarketers trying to sell me education.

Is this a trolling, robotic infiltration of some kind?  They seem to be coming fast and furious these days.
W/ this no. my experience was as w/ others below  - recd. on my homephone / landline.  ID reads as from Illinois.
Have to wonder what data it is compiling.  Nuisance, trash intrusion.

They call every Friday and it is getting to be out of control.

Number called, I said hello twice and then a computer generated voice said 'goodbye'. There should be a way to stop idiots from doin stupid stuff like this... hell I live in nc and they're gonna call me all the way from chicago?? Jeeze.... some bored geek with too much time to spare I'm sure....
