Worst Service Ever...

I have been waiting for more then a month for installation of my wifi. The agents I speak to all have a different story and some just drop the phone in your ear. Some of them answer your call and after you introduce yourself and explain what you need help with, they keep quiet and you can clearly hear the noice in the background because they're working from home. I have never received such bad service in my life. A few months ago the same happened with renewal of my contract and many warned me about Telkom and their bad service after the fact but I gave them a try and now im stuck. I literally have to call every second day just to be told a different story by a different agent. On Saturday I spoke to an agent who told me the other agent never escalated the matter like they told me they did and this is now more then a month later and still there is no solution and Im still waiting for a manager or someone to call me. Won't even help going in store because It will be exactly the same. I honestly do not know what to do anymore because every time I call in they just tell me I will escalate it to my manager and my manager will be in contact.
