Bad service and attitude

Bad service, rude staff. They do not give the customers complete items since 2018 they promised me my plug for the washing machine up untill today. I want a settlement amount they keep on telli g me that they will call me...last time i asked my settlement amount they said it is R3000 and it didnt make sense because my account was R13000 and to pay R700 for 36 months but up to date i have paid R16800 already this does not add i feel lime i have been over charged....SPRINGS BRANCH IS RUDE.
