Late fees incorrectly charged

Here I am again regarding Vodacom just a short thanks to the team with helping me with my previous query.

I’m here once again regarding the service at Vodacom. I took out a contract and on the 1st of June they attempted to debit, there were funds in my account and I have proof and even shared it with them. The debit returned as unpaid I contacted them to arrange for a redebit after I spoke to my banker. I request the lady to arrange a redebit as it seems there’s an error on their end she says it still appears paid on their side and it would return and I would be charged a late fee, I informed her that there’s money in my account she request proof and promised to call me back in 2 hours it’s been over a month. When I got a collection notice I called once again explaining my situation and that I requested a redebit and that the error was theirs as I had funds in my account and that agent actioned the redebit and assured me that he would dispute the charges so I would not be liable as I sent proof. Lo and behold today I get debited a higher amount including the late fee, I requested to speak to a supervisor who was supposed to call me by end of business and it’s almost 9 pm and no call.

I feel like I’m being de*****ed in the economy R100 matters and I want my money back, I’m so disappointed by the level of service in the contact centre it seems there is no care for the customer.
