Telkom doesn't want process contract cancellations after contract comes to an end

I logged a cancelation request for my laptop contract, because whenever you go to the store they tell you to do it online and that someone is gonna call you. No one ever called me, and that was almost 3 weeks ago. Instead today I just receive an SMS that says "Fault Reference ***4 has been closed. Please do not reply to this SMS". What kind of BS is this? Is the contract cancelled? Cause no one called to verify anything. Are these tactics to keep customers paying for contracts they no longer want? People are always sent from pillar to post when they want to cancel their contracts. You are literally making it impossible for people to cancel contract, contracts that have in fact come to an end of the initial term.
