I am shocked that the longarmer would not use your batting or thread. If she had a problem with either, she should have told you upfront and then you could have decided whether to find someone else or not. I let my customer choose their batting and thread color. Right now I have Hobbs 80/20, Legacy 70/30 and Wool batting to choose from but if they wanted something different, I would get it. I use predominately Permacore or Glide thread and have a variety of colors. I even have the thread charts in case the customer can't find what she wants and I will order it. I took classes, but my instructor never said we could deviate from what the customer wanted. Good luck in finding another longarmer in your area.
