THEY JUST DON'T LISTEN!!!

Long story short, TELKOM recently installed a DSTV Explora as part of special they had. Install went fine except that the little black box on the Explora that communicates with the wifi router didn't want to do so, so the technician said he would get back to me & and make an apt to come sort it out - this never happened!! Eventually I got hold them via their useless help line which puts you on hold forever and explained the issue. I then get an SMS saying that my line has been tested and no faults have been found??? Last week Friday (08:34am) I get a call from the same tech who did the original install saying he would come and attend to my issue, told him ill be home anytime from 13:00 and he never showed up!! This week I'm away on business in Zambia and get a call asking if i was happy with tech???? They then ask if they can make an appointment so I say no ill call them as i don't know when ill be back. A few hours later i get a call from my gate from their techs saying they're there to fix the problem - guess what i NEVER TOLD THEM TO SEND SOMEONE!! I get another call today to confirm an apt which I apparently made for the 15th of March????? USELESS USELESS USELESS!!!
