I've done this half a dozen times and still get the calls. Does not work............

Instead of responding to a 3 year old comment in a 4 year old thread, you would probably be better off trying to contact them directly:

Good Luck!

That helps nothing for the kind of calls coming from hundreds of alternating numbers. These companies do not use the same number twice in probably a year.
