Who called from 2164162172

My caller ID showed this number.

just checked my called ID, called 8 times today and it's only 5 o'clock.

Has called 7x in the last 18 hours. Never leaves a message and when you call back, you get a busy signal.

It was an Indian scent claiming to call from the Diabetic Society. I suspect a scam as I received several calls today. I blocked the call.@

Came back after being gone and found 8 calls from this number.  Called back and actually got someone who said he knew no reason why his company had called and then refused to give further information.   Then got two more calls and tried to answer -- computer generated and hung up.     Obviously a robo caller scam.
