Over 30 minutes time received 3 calls from this number. No response when answered. Never leaves message. Suspicious and ridiculous!

This number has called every 5 minutes for the past 4 hours now.  Its a so-called roofing company wanting to come out and check our roof for damage.  Caller refuses to identify the company they are supposedly representing.   Asking them to remove from their caller list will only result in more frequent calling.  Added them to my phone's blocked list and am investigating ways of tracking them down and suing them for harassment.
