Calls our home often. We answer, they don't speak and left no message. But, per Steve's comment above, "Credit card debt relief. Hmmm, sounds legit!" What a shame as I can't change phone number as I have kids and grandkids all over the country so I get 20 calls a day from calls like this I can't quit and get only few calls per week from family. Sad this type of action is allowed to continue unchecked. I've written letters to you phone companies, city, state, and federal officials. I get at best a form letter back saying sorry about your luck, don't answer the phone. Or buy some call box filter but note that it could block a call from a legit source or family member. What a choice. I will keep posting these callers and maybe someday a person will devise a way to block these greedy people.
