CID said Michigan call 231-188-9329. So they know my area code but no 188 exchanges exist. Didn't answer and never answer anymore unless I know who is calling, not even a local number unless there's a name. I've had it with these creeps that just keep calling and hang up on you when you tell them to stop calling you. I unhooked the answering machine because then they know it's a valid number, they never leave a message anyway, I just listen to it ring. By doing this I just had 3 glorious days of not 1 call. Just don't answer them people, the only way to make them stop.
