Don't know company. I answered and he kept saying  hello, hello, hello. Annoying

ID says customer service. No voice. Blocked call.

A recording pretending to be live. Block it.

I have received several phone calls from this telemarketer claiming to sell home security protection . Yesterday I told them this was private number and I was on the no call list  and this morning the same number listed as Customer Service called again . I told them this was harassment and that I'm not interested in a thing they had to say or sale .

keep calling have apparently learned  what ring answering machine picks up on and hangs up just before.
