Agents are rude and unprofessional!

My contract phone was ****** and I called telkom to blacklist my phone the 1st agent said the phone was blocked immediately and I will get my Itc number to an additional number After the call i waited..hour later nothing I went to the poloce station as i had to make a case as i was at work when it happened I then called tekom again and I waited almost 30 minutes for the call to be answered when someone picks up all i get is attitude ( agent - Tumelo Ramatejame) telling me that I have to wait 4 hours - 24 for the phone to be blocked I was stressed my kids were at home I have a baby and a 5 year old here im stuck in town trying to get case number but i need the itc number and the agents r making it difficult he said that the " back office" left so i cannot get it. I asked a manager and the line dropped. I was so angry as al my personal and banking details was on my phone and they just acting cool and calm. 3 rd agent (Johannes - told me that he doesnt have to give me his last name and said No) kept on miming me as per my request miming my every word..telling me that he doesnt know where the manager is and if he did he wont call them I was utterly DISGUSTED by his service!!!! I am so angry I am going to all social medias with this andI will request a copy of that calls... And get anyone I can into trouble..The service is pathetic! Just to get a sms a day/2 later to say that they cannot provide me with my ITC number WOW!! I need someone in high authority ro take control of this complaint as if this is not addressed accordingly Im willing to go to all social networks and all pipelines as possible!
