Bad Service

Please note on the 29th FEBRUARY I called the call centre and logged a fault. My Internet services is not working at all during peak hours from 6pm till after 1am in week days and during weekends. I have kept records with screenshots...Like always I currently have a latency (ping) of over 6000Mbps with upload 0.22 and downloads of 0.04. To this date I had 2 calls from Telkom regarding this problem, 1 was for a TELEPHONE fault and I clearly stated to the agent NO TELEPHONE fault was logged however I logged an Internet fault. After 3 weeks the Technician Justice called me his the regular Technician in our area and his well aware of the 6 year problem I have with Telkom and that it is due to the the Exchange being congested!! with promises it will be upgraded. He made an appointment to see me and never pitched up. It is more than a month later with many promises Lungile will call me.. I am at wits end now and have exams scheduled for early May however I CANNOT EVEN SUBMIT MY ASSIGNMENTS TO UNISA due to the pathetic service I am receiving from Telkom...Telkom if you cannot sort out the problem then you need to refund me for downtime I seriously hope you will assist me in this regard
