However, Caller ID often could be faked.these days.  What appears on your phone might not be a true caller ID.

Called three times today. No messages left on first two calls. Third call I answered and did not speak. There was no one on the other end. Call disconnected on its own.

Keeps calling here.... so Aggregating

They kept calling so I finally picked up and said Hello and a man said "Sorry, wrong number." Seems like a scam. Why would they call multiple times a day for more than 2 days and then go "Sorry"!

I have also received several calls from this outfit. Research shows that this company is out of business and has been out of business since 2009. This is someone using that company's name. The phone exchange 860 is for the Hartford country area and not Norwalk area where Carvill America was located. Some illicit calls.
