First I would like to say that Vodacom did credit my account as per customer care as I phoned them today in which I am thank full but I am still waiting for them to change my residential address and my ****en Name to my Married surname in which I already changed it so many times at Vodacom spend my time to go every time back to a Vodacom Shop to Change my details I have already filled in forms so many times provided them with proof of address and a marriage certificate .Hope Vodacom can please fix this because I am Married for 5years and still its not done!
