useless

I have for the past two weeks been calling vodacom call centre daily and each time no resoultion! I went in store and they said that only the call centre can help me. I have been assigned two technicians to the query and both were resolved BUT NOTHING WAS DONE! I got a new phone and did a sim swop but I can no longer purchase vodacom ticket bundles. apparently my browser settings was blocked , but it was then unblocked now tell me please why can no one see why I am getting this problem I have never had issues with ticket bundles and this is cost effective for me so I need someone to help me!! I have the same number literally even got THE SAME PHONE so please explain to me why it is no longer working on my phone! call me to resolve this
