billing on an non existing account

I have a contractwithtelkom for the past two years and it wasn't a smooth one. I went and upgraded and now I m being bul**** for the old contract and the new one now I logged a complain on receiptof invoice and again on the on the 24 September and when I went to the store tgat complaint no is not oj the system. I m not happy at all. The new contract is not active and yet I have the phone how does that one work. And worse Un the store when I went in today and there was only the technical and there were no peoole to assist in the billing or customer service. Worse now my phone is not working it's off no service. Since the 25.
