If you call the number back it gives you the option to have your number removed from their call list within 2 business days. I'm keeping my fingers crossed that they stay true to their word of removing my number because they're DRIVING ME CRAZY with calling all the time!
I called them back and an automation said they were a customer serivce place. I asked to be removed from the list, it didnt happen. I am having my cell phone company block the number completely.
