Worst service ever!

I upgraded in February and should have been on the new contract on 1 April. I've been phoning Customer Care as well as the shop in Vaalpark where I upgraded daily. I get transferred from one person to the next and one department to another without any joy! Disgusting service! I am still on the weekender package and can't buy data, except from a Cell store. Call Centre pestered me nearly daily with calls to upgrade and when I finally upgrade no one cares a damn to resolve my problem!! You can cancel my new contract and take the phone back. I will go to a Company that wants to do business and actually care for their customers. Please change the name \Customer Care"to something else"
