ADSL line fault

We have logged, emailed and called. months on months for the ridiculously slow 2mB ADSL line at our store.<br> not one effort has been made to contact or respond to test our line. we are at a stage of ripping the line out. we paying for something that has no service nor response to any issues or faults, Telkom has that old dirty habit of blaming Mweb, but sadly the online testing has kick mud into telkoms face this time. so at what point does one decide ( cancel there ADSL s**** and use a alternative wireless ?) is Telkom going to make a effort or should we cancel all three ADSL lines?
