POOR SERVICE - ACCOUNTS

Two weeks ago I requested an invoice to pay the paper for the month. Today I received an email informing me that my payment has been received and allocated. How it that possible? I have not made any payments! I phoned Media24 and explained the situation. They sent the invoice and I made a payment. This afternoon I get an email with another invoice for a different amount! What is going on with your accounts department? The Sunday paper is on debit order but the weekly paper gets paid on a monthly basis and now you inform me that the Sunday Paper is also being paid monthly. You are totally confused and have no idea what you are doing! I am so tired for explaining the situation over and over to people who do not understand what is going on. I have also asked before why the morning paper is only delivered after 08:00 each day. It is supposed to be delivered earlier. Do you think the problem will go away if you don't answer?
