Someone Is Going to Cry Here and It's Not Me (or the baby).

If you are working at a customer service call center, I think the first question you should ask the women when she calls in is "are you a stay at home mom?"  If she says yes, do not bother to argue. Do not ask her how her day is going. Do not attempt to BS her. Just transfer to your supervisor, because eventually it will get there anyway. 
Here's the deal- Stay at home moms are masters of winning arguments.  We spend the day manipulating the truth just enough to make the kids (and by kids I mean the children and the daddy) do what we need them to do in order to keep this boat/house afloat.  We are so good at choosing our words carefully that there is not even a break for thought. No stumbling, no tripping on words, no backtracking.  No room for error or we would never succeed at getting those lollipops and stickers from the doctors office away from the "kids" before they end up in someones hair (probably ours) or stuck to the floor mats of our SUVs. We are masters at maintaing control of the conversation. All of that sales training you were tought in your first few weeks on the job didn't prepare you.  That stuff wasn't designed to work on us.  That stuff was designed to work on... well I'm not really sure who yet, but it definitely wasn't designed to work on me.  
That is why, the next time the annoying, song-singing, credit report website tries to have their guy on the other side of the world (who can keep up with me just about as poorly as I can keep up with him) handle charging me for something I didn't order, they should just save him 10 minutes and transfer that call over to Tracy with the Texas accent a little sooner.
(...Same goes for the the American car company I had to call a few months back...and the internet service provider that supposedly has an office just down the street from here...)
