No internet for 3 days and no-one can help!

I have uncapped ADSL and my internet was working fine and suddenly stopped, For 3 days I've been trying to get hold of telkom to get the issue resolved, I finally got through to Mojalefa Kole on the chat portal on the website on Wednesday the 9 Dec 2015 and he confirmed with me that the technician would be at my house on Thursday the 10 Dec 2015 to resolve the issue with my internet, I actually saved this conversation as proof because I dont have much faith in telkom and lucky I did because I took the day off from work so that when the technician had been I could check and make sure the issue was resolved and no-one showed up, I logged into the chat portal and got through to the same person, Mojalefa Kole and he then tells me that the technician is not coming today (10th Dec 15) and he cannot tell me when they will be coming!... This is very unprofessional and I am extremely frustrated!!!, Absolutely disgusted in the customer service from telkom and if it is not sorted out ASAP I will be cancelling my subscription and finding another ISP!!, I can email you the chat conversation that I had with Mojalefa Kole if you need proof but I am so angry right now! Please sort this out!!!!!!
