CallerID say "cellular call". Called many times a day, picked up no answer. Called back, request no call anymore, the agent said "your phone number not in our system, so I could not do anything". Very concern about this practice!!!
Calls come everyday from this number. CID says Campbell, CA. I see different CID's from other comments. Is this a robot caller representing many unwanted and annoying sources? I do not answer. We all need to report this and many other numbers.
