Paying for services not received

On the 30th March I reported a fault as my line keeps dropping and the speed is extremely slow. on the 1st i called again and was told the faulty was resolved..... who resolved it as it was closed but the fault was still active on my side. I was called by a technician to say he would come out at 3pm on the 4th but never turned up. Our ADSL internet line is still down. Speed is still slow as its been for months and still not fixed. Please advise who the ombudsman is of Telkom so i can request them to cancel a service I'm not receiving so i can use a more reliable service provider? I have been calling your offices as well and have not received assistance. I've had to pay out of my pocket to get a service from a internet cafe as i have two kids in Varsity who could not use the internet a service i pay for and because it was down they had to use sources elsewhere. I have even contact your departments on Facebook to no avail. my complaints *** / 1040CRK300316 & again Yesterday 04/04/16
