Vodacom is useless!

On the 28th of July i logged a complaint with Vodacom because you guys were supposed to have debited me on the 24th of July. When the complaint agent called me, I said I will not hold liable for the late fees or missed debit order fees as I made arrangements with your call center's for the 24th. My debit order that went off last night now had a penalty fee of R100.88 that was added! This is unacceptable. I want that money to be reversed immediately as it's not my fault your call centres messed up! Even the person that handled my previous complaint i made it very clear i will not be liable for penalty fees.
