The 213 271 2857 callers are unstoppable, it seems, after all the complaints I've read here. I, of course, don't answer strange calls during telemarket and scammers pre-Christmas blitz. Happens every year. I've turned in the more persistent caller-numbers to the Do Not Call people, but to no avail. On those rare occasions when I confront them, the same thing happens. They either ignore my request to take off their lists or insult you, as it happened to many. Try to find a way to get back to them and speak to some one who cares, it's as hard as fiding bin Ladin.
The same as one of the above victims, I, too, work nights, 'til 5 am, and these plague of telemarketers start calling sometimes as early as 8 30 am. You'd think with all the technology we have, there'd be a way to control this scum.
I got a two calls from this number today and answered on the first ring the second time. Guy says he is from the US Processing Dept and asks if I still have my Mitsubushi. I ask who is the US processing Dept and he hangs up. Next time I am playing along with him to take up his time. And then report him to the FTC for calling a do not call number.
