Frustrated with MTN Billing department

I have been trying to get my itemised billing statement from MTN since Monday with no luck. It's Thursday today, still no itemised billing statement. I have received sms's that read "Your itemised billing statement has been emailed as requested" but when I check my e-mails there is nothing. I explained how urgently I need the statement but I still haven't received it. I received the following reference number: *** and they said the query was resolved. Nothing has been resolved on my side as I haven't received the itemised bill.
