Telkom SIM Card taking long to get activated: Telkom Festival Mall

I opened a new account with Telkom Festival Mall and on 9 December 2018 I went to collect my LTE WiFi. However the lady who assisted me, Mbali, made an error when she emailed my Order and SIM Card for activation. She was apologetic and promised me that the sim card will be activated by Tuesday 11 December. On 11 December 2018 I realised that the sim card was still inactive and I called the Call Centre twice and the agents referred me to the store. I went to the store on Thursday 13 December 2018 and I was told that the query was only logged in on Wednesday 12 December 2018. I was told that the Manager was now handling the query and in 24 hours time everything will be fine. I was given another sim card. I requested for the Manager's number so that I can follow up with her cause I realised that Telkom hardly gives feedback. I was told that the Manager's Contact Number was private (really) and she does not answer business calls. Up to now 14 December 2018 the sim card is still not activated. I do not know who else to contact. You go to the store, you dont get help, Call Cente, no help. Please help.
