Unacceptable response and service from Telkom

I have been experiencing problems with my Telkom line since November 2017. Our service and internet connection have been off constantly. It is in a working condition for maybe 2 days and the off for 4 days and so it goes on all the time. it has now been off for weeks and we keep on reporting the problem with NO RESPONSE! Last week finally someone came out and reported that our lines are completely faulty and that they will notify Telkom to get another service provider/department out to rectify/fix the lines. Finally today someone came out and informed me that there is no fault with our line!!!???? so what is the problem then? BOTH THESE COMPANIES INFORMED ME THAT I CERTAINLY DO NOT HAVE A 10 MBPS LINE!! (which I have been paying for, for 2 years!) I DEMAND A RESPONSE FROM THE RELEVANT CONTACT PERSON (for a refund on the line and a complete STOP in contract). It is absolutely useless!!!!!
