Life happens. I take care of my grandparents and their financials as well as have kids and family. My great grandmother passed and I have to organize everything for my grandmother. I get calls from creditors, credit unions, banks, insurance companies for all the policies that are the estate for my grandmother, doctors for their health and so on. Sometimes calls get dropped. While I agree, there are reasons, and the point here is a good one, even if strange.
Got a call from this number today and they left no voicemail. I called it back and got a "the number cannot be completed as dialed" message. Spam scam.
