Your cell phone company calls you to offer you a better rate. To complete the deal, they ask you to verify your account number and your birthday. It seems legitimate, but you are still not quite sure. What is the MOST reasonable way for you to react in this situation?
Give them the information they are asking for because it’s probably legitimate.
Call them back to make sure it is truly your phone company.
Ask them to call you back so you can verify it wasn’t an automated call.
Request that they tell you more info before you offer personal information.
