Don't bother asking for them to remove you from their list - they're not interested in what you want. Block the caller, and don't answer the phone if you don't know the number. Their calls are likely computer dialing programs; if you answer, it tells them to keep calling at roughly the same time of day. You can complain about them all you like, but it does precisely nothing. Just don't answer.
Also received a voice recorded message to help me pay off my student loans. Guess what? I DO NOT HAVE ANY STUDENTS LOANS!! Quickly hang up if you get this call!
These people are idiots. How many times are they going to call my cell re. student loans as I go into retirement? NEVER answer calls from people you don't know.
