Disgusting customer service cell c

I app**** for emergency data on the 19th of September 2019 there was an issue on cell c side and the data only came through the next after trying several times, in the morning when I received all the messages from cell c stating that the emergency airtime was sent and that I owe 168.00 when I only qualified for maximum of R30.00, I than proceeded to contact customer care about 5 times each time they escalated the matter leaving me with 5 reference no’s , what the point off this when this matter has still not been resolved???? Even after they telling me that it is , I was even told that the team leader would give me feedback and call me (Prettyness) till now no call nothing has been resolved, what do I have to do to get this resolved, very disappointed
