A few days ago I received an email from my ISP, verizon, well as I thought it was from Verizon. It said that they couldnt get my billing information for the month of December and asked us to fill out a form giving out our credit card number with the PIN number. That's when I got suspicious. They shouldnt ask you for your credit card PIN number. They threatened to close my account and I called my ISP and they said, NO email like that has been sent out. If you have a verizon internet connection please be aware of this. Their website was an IP Address, not a .com or .net domain. I didnt save the email so I cant state exactly what it said but I remember. Dont give out information that can get you defrauded.
A company never asks you for any such creditcard information to be filled up in a mail . Instead they take you to a portal and you fill requisite details there.
