They often call twice, hoping that your phone is set up to ring a previously blocked call if they call twice within a certain amount of time. Caller ID (even on TrapCall) only says Wireless Caller and Silverdale, WA. They try to call daily. Oddly, when you search on the phone number, you get results for fishing-related companies or websites in the Bremerton, WA, area. Who knows if those are legitimate or the number has been scammed (more likely).
