A live person! "This is Cathy from "the carpet cleaning company." As a past customer, I'm just calling to see if you have any cleaning needs at this time." Since the carpets in this house have NEVER been commercially cleaned, this is a big fat lie!
I had this number on my block list. As soon as I removed it after months on the list I received a call. Called back from a different phone and got a recorded message that I couldn't understand.
