Sim contract

Hi there am writing this review with a broken heart, I had simcard contract with Telekom and it happened that I lost my job and wouldn't afford to pay it I tried going to the nearest branch at nkomo village at attredgeville they so useless now my balance it's higher because no one wanted to help me what they say is I must dial on my personal phone to get In touch with their head office. What is the main reason they at the mall while they not helping me I want to know who to contact at Telkom head office cause the crazy amount they show me here am not gona pay it.... It's either they reduce it or I can't pay it thanks.
