I called Bank of America, and the lady said that it was a promotional call, I asked her to stop all calls to my home unless it was a fraud alert.  She said it would take up to 30 days for the calls to stop.   Hope that helps.

I answered...Hello...and all I got in return was heavy breathing....for 30 seconds...then it hung up !!!!

I keep receiving calls, usually in the evening, from 216-545-8326.  I didn't pick up the first couple times they called because I didn't recognize the number from Caller ID.  About the 4th or 5th call, I answered, and someone just started moaning, and then asked if "Dolly" was there.  When I said that this was "Dolly," they started singing, "Well, hello Dolly, well hello, Dolly . . . ."

Have received numerous calls from 2165458326. When I answer there is silence. They never leave a message when the answering machine picks up.
I have a telezapper, maybe that will discourage the repeat calls.

Whoever they are, they're still at it.  Got a call the other day - one of several over the last few months.  I don't even answer the phone now that I recognize the number.  Never a message left.  Very suspicious.
