Impossible to use. Everything was going great until the first of the year when UHC changed from Walmart fulfillment to this mess of a company. Starting to think its outsourced to China. Keeps saying I'm not in the system, obviously I am and have been for 15 years. I gave up and ordered through the mail over a month ago and have heard nothing there either, no email reply no nothing. So,I'm going straight to the top of United Healthcare,higher up if need be. I will report for Medicare fraud.
