Oh my, that is not the "Medtronic Model" of patient care. You are going to need to be your own advocate to get the service and care you need.

It is the responsibility of their tech to help you get the machine set up and operating optimally. Please contact her, and work your way up through their customer service to get the help you need. They may need to assign a next-level technician if this is not the usual use of the device. If necessary, get your doctor involved.

Do you have contact information for the technician? If not, look into the material they gave you about the device to find it.
