EPP Account Frustration

My EPP rates were all moved to Business mobility and my bill is now extorionate. I have now lost track of the hours I have been on the phone trying to communicate with staff who either don't listen, don't understand or don't care.  I now have phones and lines I didn't order, have over 20 email threads from so many people, I don't know where to turn.  I have tried to reach out to escalation teams, where people do not value your time or care to understand how to help.  This chaos has been ongoing since February. I still do not have answers or a resolution to the mess.  

I had two agents offer to organize and help and they just disappeared??  Today, I was told that the supervisor of the escalation team was the only employee left who could help.  THere is no supervisor for that person, no other staff

Where does this leave people?  I also tried emailing a couple exectives who list email info on the site, however, and no surprise....NO RESPONSE!!
