Vodacom Business not user-friendly at all!!!

We have a Vodacom Business account with a few lines attached to it. I wanted to know what are the average number of minutes that was used on two of the lines per month over a period of time as they are up for renewal, I called the call centre and they provided me with the balance of the minutes currently available. I told them that was not what I wanted. They then told me I could apply for the itemised billing statements. I told them I have those, but it means I have to sit with a calculator and add all of them up manually. The agent told me so would she. I then lost it - surely this information must be available at the press of a button? It always used to be printed on the invoices, but at some stage they stopped doing it. I also wanted to upgrade a phone online, just to find out even though I am given the option to do it, when I get to the final stage, I can actually not do it. Vodacom's systems are not on a level one would expect and creates more work for a business, instead of saving time. Good customer service means supporting your customers and making their lives easier, not seeing how many obstacles you can put in their way! Pathetic!
