Vodacom online Sales the biggest headache

I placed an online order at Vodacom on Sunday. On Monday i called Vodacom to confirm that everything was fine with my order. I was then informed that i had to personally sign for my order, i had to then change the address as i work far from home. The call centre lady said that she had changed the order and also said that the order wasn't confirmed yet, someone will call me to confirm. By Wednesday i had not received a call yet, i again called Vodacom. The call centre then informed me that they do not have stock and it will take 7-14 days. One hour after my call i received a sms to say that the order has been processed. Friday morning i receive a sms with the wrong address from RAM. I have been on the phone with Vodacom for more than 30min and have been transferred from sales to upgrades to online sales. I have asked to speak to a manager every time and no one is willing to assist. This is the worst service i have ever received from Vodacom.
