15 years and the problems continue!!!!!

Since I moved into my current house 15 yrs ago, I've had a bad line. A Telkom official then told me to install ISDN and my problems would be over. I did it and my voice line was fine although It cost me much more than a regular line. All along I had TERRIBLE ADSL. I would at times be without internet for 6 weeks at a time. I tried getting Afrihost to manage the ADSL by not even they could do it. Frustration forced me to install a wireless internet service which I cancelled because Telkom Menlyn promised me 40MPS using their VDSL service. After a lenghty process of cancelling ISDN, reassigning lines etc,over a few months, I now have a VDSL modem, a HORRIBLE NOISY voice line and virtually no internet connectivity. ENOUGH IS ENOUGH. Why promise all these nice things if you KNOW you cannot produce. In an attempt to resolve this issue I physically went to the Menlyn Telkom store to see the manager. She was not there and they gave me a number to call that DOESN'T WORK. I am at the end of my wits. TELKOM, IF YOU CANNOT PROVIDE ME WITH A SERVICE, SAY SO AND ALLOW US ALL TO MOVE ON. STOP WITH YOUR GLITTERY ADDS AND ALLOW COMPETITION TO IMPROVE OUR COUNTRY'S CONNECTIVITY ISSUES!!!!!
