Billing sytem ,rude customer service agent

Good day I have an issue with Multichoice,the ir billing system is a mess when i log in to my profile i see tht i have to pay double the amount that i pay,i first made contact with their agent on facebook i was told i have two packages and have upgraded i told the agent i have never upgraded i then requested the voice recording and the date but was not assisted i was told they escalating my issue,same day after an hour i called in an agent by the name of (Zicina)not really sure about the name put me on hold for 30 minutes??she then told me the same story that i have two packages wich i have upgraded i tried to explain to her she hung up the phone on me after i was put on hold for half an hour,Multichoice need to fix their billing system im not paying double the amount for all the repeats they show us why would i take an extra package that i know i wont be able to pay,i need them to fix their billing issue or cancel my subscription
