Unaccounted subscriptions on my account

I have had 2 contract's with vodacom for the past 5years. For the past 3 months I have not been using my contract cell# ********** 596 and ********** 141 because it is closed due to non payment. Normally I pay a max of R200 for both my numbers but now u am being told to pay R2521.92 due to subscriptions I know nothing about! The agents are so rude and dismissive n recently they dropped the phone on me! Everyone is just passing the buck! Can some who knows what they are doing call and assist. My reference numbers are1- ********** ********** and 1- ********** ********** support specialist
