Unbelievable, unempathetic, lack of understanding, service.

I am so mad at Vodacom right now! You recently upgraded my business mobile. To be in line with what I was paying and the monthly calls I was making, the salesperson put me on a Smart-S package which gives me 200 minutes airtime. I expressly told them that this is in order with me as I could always top-up should the need arise. This is crucial to me, as I run a business from that phone. Imagine my frustration when I tried to buy airtime today and couldn't. With numerous business partners, staff members and clients waiting to hear from me. I completely lost my sense of humour when the call centre told me that I was on "open line" and couldn't top up my airtime. Why, for the love of the universe, didn't Vodacom representative tell me this and rectify the problem at the point of sale? It completely baffles my mind, especially as this is a business account. Didn't it, for one minute, cross their mind that this is a business and it needs access to constant, uninterrupted communication facilities. Furthermore my invoice on the same number is being submitted to the previous owner, despite us having changed ownership and this having been implemented by Vodacom. I have previously requested them to rectify this telephonically and I was told that they could not assist me on the phone. I receive the monthly statement of account reflecting that invoice, but Vodacom cannot send me the invoice without written instruction, but they can change your package and sell you a new phone by means of a simple telephone call. How do you figure that?
