Worst Service Yet

For the past few months I have asked RCS and Macro to change my email address so that I can receive my Statement as I do not use the old one and still not only do they not reply but obviously not Actioned. I decided yesterday that stuff it that if they cannot action something that easy rather cancel as the service is shocking. I went online to log a request on teh RCS website and it kept giving me errors. I then called ********** at spoke to Nele yesterday 04.10.2018 at 08h22 to request a settlement amount as I rather wish to cancel everything. She gave me a settlement amount that is valid for 5 days up until the 09th September. I then asked her if I have have this in writing where she starts singing another tune by telling me that it takes 24 hours to generate the letter and get this, the amount might change. When asking why is it that when I request it telephonically its valid for 5 days but if the letter is generated a day later why it would have a new amount. She could not answer. I asked to speak to a manager, then got put on hold and was told the TL is not in yet and that the Supervisor will send the letter but can only do so at 17h00. I know right, is the supervisor not some form of management structure? Needless to say its now Friday the 05th October and is now 12h39 and still I have not received my settlement letter!!! Why is it that you want to apply for credit they jump on you and even have people in the store as at Makro by the entrance they armed with a Tablet asking can they check if you qualify for credit. Is this not against the NCA and Consumer Protection Act by recklessly offering credit and then yet provide you with such an appalling service and we must just accept it?
