I was being harassed by this number, and so did some investigating. The company, collegeforcareers.com, is owned by Marketing Direct/Marketing Links Direct Inc. of Ft. Lauderdale, FL. Their phone number is 954-727-1323.
All attempts to contact them and be taken off the list have otherwise failed. Hopefully they take me off now that I have located and contacted their main office.
This whole thing is getting really annoying. I blocked 2 other numbers recently and they do the same thing every time, move to another one....this time the one listed. I don't get what their problem is, it's very clear that I don't want them calling my cell phone
