Supersonic - Slow at service, even slower on deliver but more than happy to take your money for a line that doesn't work and that has been cancelled A MONTH AGO

What an awful experience and this was right from the start when I first signed up. It took a whole month and a half for the fibre line to be installed- mind you the person that installed it decided to do his own thing because the line did not work. We waited 24 hours which lead to the next week and BOOM !!!!the whole Month was finished and STILLL the line was not active. The calls i made to supersonic were useless because NO ONE- i repeat NO FREAKING PERSON new what was going on - YES not even a manager who by the way i waited on the line 15minutes for and did not bother to take my call or call me back for that matter. So in my house im sitting with a box and a router that doesn't work- IT has NEVER worked from the time it was installed - NO one came back to check what the issue is even though i had been calling days on end. ..NOW what irritates me the most is that they have the nerve to tell me that this THING that doesn't even work cannot be cancelled right away and that I must give 1 months notice - FPOW WHAT EXACTLY???? for a fiber line that has NEVER worked ??? AND OFCORZ they have now taken a payment of R996????? AGAIN what is the payment for when the line doesn't work? What is the payment for when i cancelled the line before i could even use it?? What is the payment for when NO one At Supersonic knows what's going on?? What is the payment for when the customer service is so terrible, they put you on hold with the HOPES that you will end the call ( yes this happened to me ) and the many transfer between the various departments where NO ONE does a WARM TRANFER ???? I could go on and on about this so called supersonic who doesn't want me to cancel because I must give a 1 months notice for a line that does not work!!!!!!! Too bad I Cant give a ZERO star rating, hell they not even worth half a star
