Poor client service

I sent some mails to Discovery Health regarding admission numbers I need for the hospital. I need this number, otherwise the payments have to come from my own pocket. The firat mail was sent on 24 Feb 2018. No response. The secons mail on the 28 Feb 2018, no response. My third mail was sent on 01 March 2018, again with no response! How poor is the client service?? What if my request was an emergency? Totally unacceptable!!
