Who called from 3602103456

have rec'd 4 calls from this number already today.  no message, nothing said at all, just dead air.  what's this all about?

A woman with a heavy foreign accent called asked for me by name and asked if I was still testing for diabetes.  I told her yes and she tried to tell me how I could possibly receive free supplies and a free test meter.  I asked her who she was calling through and she said US Diabetic Supplies. Since I did not call them to initiate this call I told her I was not interested and hung up.  Caller came up from Washington
360-210-3456. When I tried to call this number back of course it was not a working number.

10 calls....nobody there....very annoying.  Kinda scary. Im 77 years old.

don't know the number? don't answer it calls 2 3 times a week

keep receiving CALLS ..........
Won't QUIT.
