Just received a call from this number. Unknown and no VM. Did not answer!

I just got a call again (the fifth time today) and finally someone answered. He introduced himself as "Robert" from "College Network." He then proceeded to try to ask me some questions about college. I told him not to call me again and to remove my number from his list. I will report this to the Do Not Call Registry.

Have called me 4 times today and when I tell them it's a wrong number they get very rude and hang up.

Number calls and leaves no message. They called a third time today, I answered, and they hung up. When I try to call that number back I either get a busy signal or an error message.

these company calls and just ask for someone and hangs up

Just got call from them first time. Same responses as above

never stops calling asking for unknown person when i do answer tell them they have wrong number and they still keep calling so rude.
