Express Scripts ESI Inaccurate Information and poorly trained supervisors St. Louis Nationwide

Express Scripts is the worst organization I have ever dealt with!  They're business processes are substandard at best, the "supervisors" blatantly provide inaccurate instruction just to get you off the phone, and at the end of the day you literally have no wins because Express Scripts is not your choice, it's your healthcare providers decision.  They run a dictator type organization in which they do what they want and expect you to follow their rules. 

I am appalled at Express Scripts unethical handling of billing procedures, lack of effort to address a flaw in their notification procedures, intentional use of misdirection, and lack of knowledge about why they have procedures in place that make the primary account owner responsible for all charges (w/o notification or approval) but lack of ability to control what can be charged.  Insurance is not a luxury, it's a necessity in which I am fortunate enough to be able to provide for my family; but as the primary provider of the insurance; Express Scripts has gone out of their way to make being a responsible consumer and benefits owner impossible! No reasonable business owner allows the primary beneficiary to add people to their account out of necessity and then tie their hands by saying that everyone on here can use this account without limits and at the end of the day we will never notify you that your covered persons are incurring charges without paying them, and then throw those ignored charges on your credit without ever telling you once that there was an issue.  This companies behavior is highly unethical, inappropriate, and needs to be addressed.

How is this company still in business?
