Vodacom *****ing money

I did an upgrade on vodacom online. A day later I received a message to say the phone will be delivered the following day. The following day the courier said vodacom asked for the phone to be send back. Since then I have contacted vodacom online 13 times spending hours on the phone trying to sort it out. More than 2 weeks later and I still don't know what is going on. I have been receiving the invoice and the contract has been renewed and paying for the phone but I still have no phone. Now Ai am asked phone various department but I just don't get any answers. Nobody can tell me what is going on. Last week a lady said she will cancel it and I can today go into any Vodashop and upgrade. Again I wasted my time as nothing has been canceled. I really do not know what more I can do. So after spending more than R200 on calls and petrol I am sitting with a contract that has been upgraded but do not have the phone. I request to be contacted by the CEO or else this story is going to the newspapers. Mail me don't phone me.
