Bad customer service

I called on the 31 August 2018 to get the final balances of my account to close it, all my accounts have been done other than Edgars as I was informed that I had 2 different accounts and that the one I closed was not the one with the default on. After going back and forth, at my own expense, calling, emailing, pulling reports etc (not to mention waiting for 2 - 3 weeks on end for a reply), I get a settlement amount to finish off this account - all in total from September 2018 to December 2018, I have finally decided that I cannot do this anymore and asked what the settlement amount was, being December 30% or 40% settlements are usually given however when I spoke to Happy from the customer service department at MBD and other agents, I was told that the only settlement they could give was R1000 and that its at a click of a button and cannot be over-ridden (which I find ridiculous due to the mere fact that I was the one spending money and time contacting them back and forth, waiting for replies, even included the Ombudsman without any resolution, hence why I decided to rather pay it now off and look at the attitude I get from Happy Makhubele) - It's not enough that you have to wait nearly 30 minutes for someone to answer the phone, weeks for a reply via email (all of which I can send to whoever needs it) and when you decided enough is enough rather pay it off a R1000 discount gets given (with attitude)!!!
