User reviews for 510-330-4963
No answer no message left. just keeps calling every day! Often 2-6x per day! Serious pest. Suspected robocaller.
I asked the caller who they represented but no answer to my question. Caller continued to verify my address and name.
Yesterday the number 5103304963 phoned me a few times. I couldn't answer it. Later I called it back. I was rejected. I called it later again but there was silence on the other side. I think it is nothing important. Probably telemarketer with another ad or an invitation.
