Why phone scams are so difficult to tackle
Many of us now refuse to answer telephone calls from an unknown number, for fear that it could be a scam. And we dread receiving a text message, purportedly from our bank or a delivery firm, again due to concerns that it might be from fraudsters.

Possible scammer. Auto dialer. Does not leave a message so it is probably some bogus caller looking to steal your private information or another of the many duct cleaning services.
Best to avoid and ignore. Never give your information over the phone.
