Well if this is true what you say, it looks like someone in the O2 shop was messing around with your phone and then deleted the message from your sent box! It is absolutely outstanding that they could do something like that and i really feel bad for you. It looks like there is no way of solveing this problem than explaining over and over what happend and never stop no matter what happens. If I were her i wouldn't beleive you either because it does sound like a terrible excuse. But if it's the truth, then you shouldn't give up! G
