I had the same, when I called to ask if I could try some other sets, they couldn't find me. But maybe the issue was that Kings have shelves full of the 4 different pumps that they give the patient a choice of. Not only pumps but sets and cartridges as well. I came home from my second app after starting with insulin with an animas reusable bag(you know the bags for life) full of sets and cartridges and extra battery's . Both hubby,kids and myself calculated that I had walked out with about £500 or £600, pounds worth if not more in consumables, and I had to place my first order in Jan of this year. But my DSN also called and emailed my registration form and I am now on their system.
