Telkom not sorting out dsl and phone line problems

I have logged 2 faults in the last week Issue 1 was looked at but closed when I told them it is not resolved I then logged another fault My internet has been intermittent for over 10 days now I have had 3 different agents come to my house Every time I have to explain from the top They have changed ports in our complex They have changed ports at the exchange The second agent mentioned there is a bridge tap on the line He will refer to a broadband specialist The third agent did not know about this He did not even understand what it meant but he said he will speak to a specialist and the specialist will reroot my line I dont know if this has been done The internet is still intermittent goes from 4mb to 0.5 to 0 and then up again I have had to use 3g for work and it is expensive Now through all this my landline has also suffered First I could not phone out which they fixed but now no one can phone in It says my number does not exist It is beyond frustrating to deal will all these agents No one seems to know what the problem is Then my phone line also suffers The third agent even suggested that it might be my rooter My rooter would not cause dsl and telephone lines issues nor somone finding a bridge tap issue I need answers and need it all fixed as it was
