Vodacom privacy protection password

My vodacom phone yesterday when I turned it on required a privacy protection password and I went online to check what was it for and I saw to many people complaining about the same issue which they say is the software vodacom put on their phones. I do not remember putting a privacy protection password and therefore do not know what is it so I logged to my vodacom and left a message there and no reply and today I called the call center and the agent does not know what I am talking about and she said she can only help me with pin and puck and no surprise there as I have read online that they are useless and know nothing. Tomorrow I am returning the phone where I bought it since it is still under warrantee since vodacom cannot help with their products.
