No Response and Bad service

On the 29 July 2015, I purchased a 20Gig LTE router from Telkom. On the 05 August I logged a case (***7) as I did not receive any download or upload speed even close to what is being advertised. On a good day I would get about 5Mb/s download speed and 150Kb/s upload speed compared to the advertised 15-80Mb/s download speed and a possible 15Mb/s upload speed. When I purchased the product the sales person and I checked that I was located within the LTE covered zone.<br> <br> After no feedback I contacted Telkom on the 14 August and to my surprise was informed that the case was closed. It was said the technician tried to contact me. I checked the time and date supp**** but could find any trace of anybody trying to contact me. I re-opened a new case (***1)<br> <br> After no feedback yet again I contacted Telkom on the 24 August and was told my case was escalated (483729). Every time I was told that somebody would get into contact with me but never does. After no feedback yet again I contacted Telkom on the 14 September, 09 October, sent an email 21 October and the 26 October just to be told yet again an email is being sent and that somebody will contact me.<br> <br> Pathetic customer service
