My employer switched to Anthem/MynextRx on 11-1-09; I registered with them soon after. Since then I've had nothing but problems getting prescriptions refilled. They are supposed to call me when I have a refill coming up; they don't call. I've emailed about not getting prescription refills; they don't respond to emails (even though they say they'll email back "within two business days").
My wife is on the exact same plan and always gets a call when a prescription refill is due. I mentioned this to one of their customer service representatives today and all she did was switch me to the pharmacy, which is automated. The automated voice asked a question: "what is your ID number" and then proceeded to read back the wrong number; also read back the wrong date of birth. Clearly, the voice recognition program they use isn't working well.
All is all, I spent 17 minutes, mostly on hold, before their system finally recognized I needed a refill. Had they called me, like they advertised they would, my refill would have taken less than a minute to process.
For what we pay in premiums, the service should be excellent; it's not.
