Hate to say it, but by calling back and getting on their 'block list', you can end up getting even more calls as you've let them know they have a live number
We received a few calls from this number today and yesterday. They never leave a message. I called back today and the recording says to push #1 to be put on the do not call list. That is a weird thing to have on your company recording? I wish I would have read the previous post about that. I appreciate this service here.
