Breach of contract

I originally reported a fault for slow connection on a LTE-advanced on the 26th Feb with fault number ***1, I later found out that the entire area I live in has not had LTE connection since the 2nd Feb and they are \investigating\" the issue. It is now two and half months later and they are still \"investigating\" the issue. The incompetence of the call centre cannot give me an answer and cannot even provide me with a contact person to find out more info on my case. Telkom staff cannot even follow their own terms and conditions of escalating the fault as nothing is clearly being done by it. The call centre have promised me everyday this week to contact with no calls as yet. Instead I have to call everyday and be put on hold for 50min at a time for them to eventually end the call. The call centre \"team leader\" cannot even get the act together to contact me back so I ask you Telkom why appoint a team leader if they cannot even provide information or even escalate the fault as per the terms and conditions. The only response I receive is an email stating the fault is under investigation with a completely new ref number: ***2, ***7. Useless service provider Telkom is. "
