This number is a charity masquerading as "Plano Lion's Club". Told them to go to hell.

I've gotten calls from:

972-253-3401
           6801
           6700
           6040

These are all a telemarketer for charities (Plano Lions for one). Here is what they do. The robo system calls, then hangs up! If you answer then your number is flagged in their computer as a callback. Then they call, and call and call. They call at 9:01 in the morning, they call at 8:59pm. These computers are programmed to call at many different hours to see when you answer. Then they program them to call during those "answered" hours.

I hate these frigging things and I'm a programmer (I write computer programs that run payroll).

They get away with it because charities are exempt!

A poster for 1 of these numbers says they call asking for donations for a number of different charities - because they're a charity, they get around the Do Not Call list.  DON'T ANSWER - the robo-diallers then make a note that you're a "good number" & they put you on the list to keep calling back.  Save yourself the aggravation & just don't answer 972-253- (whatever).

How is that any different from not answering and voice mail picks up?

My phone rang while I was on another call. All that showed on caller ID was (972) 253-6700. When I switched over to answer the call I heard nothing but a dial tone. I tired to call back and got a busy signal. So I guess my number is now on their "good" list.
