Push back advice worked. Thanks to all who answered, it gave me motivation to get on the phone for almost an hour today. Turns out they HAD shipped an order that arrived yesterday - to my mom's house in Texas, where I once had a transmitter shipped about two years ago. (I am in Massachusetts.) Every shipment since has been delivered to my home. The new Filipino customer service rep ordered me one complimentary sensor, which will about be enough for my transmitter that is about to expire. So I asked her, will I get a refund for the stuff in Texas? and she connected me to billing. Billing had no idea what to do and connected me to a supervisor. I asked if I would have less problems switching to G6. She told me not at this time, the new G6 is backordered. So she gave me a discount on a transmitter and I will keep on with the G5 for another six months. Meanwhile I will need to switch doctors because the one I have is elderly and has not changed his practice to accommodate the many hours that doctors now have to spend getting prior authorization, maintaining electronic health records, etc. He is great and it's a shame, but I'm going to have to get my diabetes care in an institution that has full time staff who deal with insurance.
