Fed up

I'm fed up with telkom, the call centre agents are useless, I received my telkom lte router on 24th of December 2018 they promised to activate my account within 24hrs,i called them 3 days later to notify them my contract is not yet active only to be told they delivered the wrong Sim card that belongs to someone else, I log in a case and today is the 10th of January its been a roller coaster I'm sent from one department to the other and it seems it not any body's responsibility, I have called the call center but no one seems to be able to help??? can someone please take responsibility ****om
