spoke with my friend about your L situation (asking for more money). She said that you should just call her up and find out what changed and prompted her to send you a bill. She said it will be the easiest and the most direct way to straighten it out. L's tend to be busy and sometimes they forget things that are now written down but juggle their memories and they will be first ones to admit to their mistake (the whole scale and justice thing?). If that doesn't work, let me know what the conversation was like and my friend said she'll try to help more at that time.
