Who called from 9512911097

The call went to my voicemail and the low life caller did not seem to realize it. He said " Hello, how you doing today?" then muttered something unintelligible.

very annoying to receive a call without a true identity

Picked up, said Hello twice, then hung up.  Now blocked.

Called asked my name I said who are you called me? She kept asking to confirm my name I said take me off your call list.  I called back and it is an invalid number.
