Horrific customer service. None of the information...

Horrific customer service. None of the information on their Find a Provider Locator is up-to-date. None of the information given by their customer service was up-to-date. BCBS also refused to confirm whether a provider was on or off their insurance plan before I saw the provider and submitted a claim. How are you supposed to find an in-network doctor, if their directory is out-of-date and they refuse to confirm whether the provider is in network?
