Telkom bad wifi

I have uncapped and pay about 947 rand. Over the past 2 months I have contacted Telkom because of my slow wifi. Trust me I understand when I'm being Throttled. I'm not to sure about my dates but last month I went from 4mbs to 2mbs in like 2 days, funny story I wasn't home. I didn't have time to argue because ultimately the people in the call center can't really assist. This morning 3rd April I contacted them because my wifi is very very slow. I mean this is really a bad service. I didn't want to use a social platform but it seems like nobody can help me. When I called a month ago a lady helped me and told me if I want to cancel then there would be a penalty, understandable but also bit unfair. I'm canceling because of bad service something Telkom is not living up to. 947 is a lot of money. Another funny story is that we only 2 people in the house on the wifi, my wife and I. I'm at work during the week! I went as low as asking them to upgrade me to Fibre or even a faster speed like 13mbs but they said I will have to take out a whole new contract. Telkom it is your fault that's why I'm playing the run around. The past week I have been working from home, what a nightmare. I haven't missed a payment, I don't want to downgrade all I'm asking is that my wifi work consistently without me rebooting my router 6million times or removing the Sim. Imagine by the 17 of the month I'm on 2mbs what? I'm at work everyday. Although I'm using LTE guys come on please, please it's the 3rd of a new month, fresh data but still not enough. I don't know what lame excuse will be coming now.
