Nếu có những cú điện thoại ở đâu đó gọi đến cho ḿnh mà số Area Code là :
284, 649, 876, 809 và nhắn ḿnh gọi lại cho họ th́ tuyệt đối đừng bao giờ trả lời
Lư do: Những area code này thuộc một tổ chức lừa gạt Quốc tế, nếu ta gọi lại chừng vài phút thôi là có thể bị trả vài ngàn đô theo giá biểu cuả họ quy định.


WARNING
Costly NEW AREA CODE: READ AND PASS ALONG
809 Area Code
We actually received a call last week from the 809 area code.
The woman said 'Hey, this is Karen.
Sorry I missed you- get back to us quickly.
I have something important to tell you.'
Then she repeated a phone number beginning with 809.
We did not respond. Then this week, we received the following e-mail:
Do Not DIAL AREA CODE 809, 284, 649
AND 876 from the U.S. or Canada.
THIS IS VERY IMPORTANT INFORMATION PROVIDED TO US BY AT&T. DON'T EVER DIAL AREA CODE809
This one is being distributed all over the US ...
This is pretty scary, especially given the way they try to get you to call.
Be sure you read this and pass it on.
They get you to call by telling you
that it is information about a family member who has been ill or to tell you someone has been arrested,died,
or to let you know you have won a wonderful prize, etc..
In each case, you are told to call the 809 number right away.
Since there are so many new area codes these days,
people unknowingly return these calls.
If you call from the U.S. or Canada,
you will apparently be charged a minimum of $2425 per-minute.
And you'll also get a long recorded message.
The point is, they will try to keep
you on the phone as long as possible to increase the charges.
WHY IT WORKS:
The 809 area code is located in the Dominican Republic .
The charges afterward can become a real nightmare.
That's because you did actually make the call.
If you complain, both your local phone company and your long distance carrier will not want to get involved and will most likely tell you that they are simply providing the billing for the foreign company.
You'll end up dealing with a foreign company that argues they have done nothing wrong.
Please forward this entire message to your friends, family and colleagues to help them become aware of this scam.
