Turn Around Times and lying to clients

I called and requested a follow up for the itimized billing. The consultant I spoke to yesterday at 09:30am told me I will receive it shorty. 45 minutes later I called again! I was told it takes 2-24 hours, is waited patiently. This morning I call. I'm told the billing was not working yesterday and my query will be handled on Monday. WHY did they lie???? They should've told me that billing doesn't work on weekends. The lady I spoke to today is telling me that my query has been Prioritised. I Need what I had requested URGENTLY!! MY PHONE CALLS FROM JULY - SEPTEMBER!! STOP LYING TO CLIENTS ABOUT TURN AROUND TIMES. IF THE TRUTH WAS ADVISED TO ME. I PROBABLY WOULD HAVE UNDERSTOOD.
