chancers that will do anything keep getting money from customers

I settled my account on 25 April 2019 and I called to see if it has reflected so that I can go to a walk in store and close it they had added R20 call fee on 26 April 2019. Who called, when I spoke to their sales rep on 25 saying I have settled and I called them. @hoome better reverse it or I am logging a complaint with the relevant body. chancers!
