I called my cable company's customer service the other day, and based on some previous negative experiences I had, I told them I was my wife.  The account is in her name, so she needs to be the one who makes account changes.  Some companies will let you call and have the account holder nearby to give their verbal blessing.  But I just told them I was her.  What are they gonna do, not believe me?  Ask me anything.  I know her birthday, her mother's maiden name, her social security number, the hospital she was born in.  I know where she's lived, what cars she's owned, the name of her bridesmaid.  I know the answer to every possible security question they can ask.  That effectively makes me her.  Aside from the customer service rep being a little thrown off at first, it worked like a charm. #business
