I keep getting repeated calls from this number, which I do not answer. This has been going on for several weeks now. The calls come from Los Angeles, CA. Their aggressiveness is over the top.

Do you know what it is for? I'm getting them at the office and it is driving me insane. I pick up but no one answers. If I try calling back no one answers.

Johnathon from this number called and told me he was from our phone company. When I ask ATT he said yes, he started asking if I was happy with my phone company ? As I tried to ask him what was the point of the call He told me very rudely "Shut UP" and disconnected the line.

They are relentless and I tell them off every time they call and I would say I am rather a nice person.  They can barely speak English.

told me he was calling from our phone provider, told me that my boss told him to call me while I was at work, I asked my boss if this was true and he said no.
they are scammers and liers, do not trust these ppl
