take your money but deliver no service

i have been a Telkom pinnacle customer for years.i have had various products, I moved a line in December 3 2013, I had adsl uncapped 2 mbps. the line is ***. all went ok until april 2014, since then connection speed is slow I never get above 1,2mbps per second lines drop all the time. Telkom hoaxed me sent people here tested the line etc etc for 10 months. now the cretins are trying to get me to upgrade.i went into a store and afer being persistent I was told because I am on UNCAPPED TELKOM MADE ALL UNCAPPED CUSTOMERS ADSL LINES SLOW SPEED ETC ETC ETC SO YOU CANNOT USE IT EFFECTIVELY OR DOWNLOAD.<br> these fools for a year has made me lose business I cant send a complete email, and I do not download a lot at all, SO THESE ******* DECIDED THAT THEY WILL SLOW MY LINE DOWN SO THAT THEY CAN FORCE ME TO DOWNGRADE TO ANOTHER PACKAGE NOW. I HAVE NEVER ABUSED THE SYSTEM THEY HAVE ABUSED THEIR OWN SYSTEM.<br> SO TELKOM CRETINS WHAT ARE YOU GOING TO DO TO RECTIFY THE MATTER !!!! OR WITH WHAT LYING EXCUSE ARE YOU GOING TO COME UP WITH ?????
