Called 4 times in a row. Ended up blocking the number. Called it back from a different line and received a recording about calling customer service and that all of their agents are busy and to email them at [email protected] and when you press 2 you can have your number removed from their internal do not call list. A search of that email address brought this up http://kfor.com/2017/01/24/mysterious-call-wi ... hing-your-head/
