Six calls in one day, all unsolicited.  When I called back and asked to be removed from their call list, they said they wouldn't take me off.  Doesn't make sense.  Ridiculous and annoying!

Indian call center who called me at 530 AM CST to tell me my auto loan was approved.

There completely scripted, i called from a different phone number and called them back and they start with the same stuff on a number that's not even in their system.
