Ongoing problem with ADSL

I am battling since last year for Telkom to fix my ADSL connection that keeps going of on daily basis. I have a string of reference numbers and a number of technicians has been to my house to try and fix the problem but nothing seems to happen. My last fault was logged on 25/02/2015 and after this I am still battling to keep my internet on. I am told that I have the old cables that van only handle 2mbps while I am suppose to be on 4mbps.<br> My child is doing home school and is critical for me to have internet to do assignments and write exams. It has happened that I have to use my phone to submit exams and all of this is making her fall behind.After logging my last complaint *** I seemed to be blocked and can only try and escalate the complaint but this makes absolutely no difference. I have tried to change service providers but was told that I would have to pay a penalty and that they use the same technicians that cant help me now, I have asked if there is not another option available for me to shift to but no reply from their escalation center has bee received.<br> I have had this line for about 1years and ADSL for more than 3 but these last couple of months ...<br> Please help!
