Telkom not aimed on customer service

In 2017 we had next to no internet on our 4mb adsl line and when we had internet it was not even close to what we are paying for . telkom thaught they can pay us back by giving us 1 gb free but we had a 20 gb cap on the line which we never passed cause the internet was barely on this lasted from march 2017 all the way till november 26 when we made new contract for uncapped hoping we would get better internet service it worked for the month of desember up intill 20 desember then the same problem started we called and they said they put us on a 2mb line and not a 4 mb like that we were paying for not to even mention that when the line works the download speed barely gets to 1mb/s and that just makes me so angry and when you call the help line the people are so incompentant there because all they can do for you is lock in a fault and that never makes a difference so im so fed up with telkom and i know with proof that our internet line can go all the way up to 3.35 mb /s
