RUDE call centre

Customer service at this company is a joke. both the call centre agents and the manager do not know how to deal with Irate customers. Training needs to be arranged I feel. I paid the outstanding balance on my account on 31 August 2018. I email the RCS group to close my account on the 3rd of September. No one got back to me until the 12 September 2018 where a settlement letter was sent to me, after they charged me fees on the 10th September. hahaha I paid the R129.33 however I want that to be refunded to me, what kind of company takes 9 days to get back to their customers? I phoned this morning at exactly 11:05am and the call centre consultant I spoke to was rude and made me feel like I am wasting her time. She proceeded to argue with me about this and when I told her to let me speak she put the phone down on my ear. I phoned back and requested to speak to the manager and he also treated me like I was wasting his time. WOW! He said that it will take him time to find the call because the Rude, pathetic call centre did not even take down my details. I am so upset that now I will be enjoying contacting social media as well as the CEO of the company and trust me I will find out who he is.
