Telkom LTE pathetically slow

I have had my Telkom LTE router for about 6 months. Before I decided to go with the LTE router and Telkom contract I had a sales rep come and do a check and demo of the device in my home. This went very well and I was amazed to see download speeds of between 44 Mbps and 14Mbps with upload speeds of between 2Mbps and 6Mbps.<br> Since about 1 and a half months ago this has all fallen apart - and now I have to deal with Download speeds of no greater than 3,7Mbps and as low as 0,5Mbps with upload speeds still in the region of between 2 and 5 Mbps. I called into the call centre numerous times stating the problem and all the techs would do was advise to reset the router, switch it off and on and so fourth - end result NO improvement - after numerous calls and expressing my concerns that the so called tech guys were actually not offering me any tech support they said this would be escalated and I was given a case number. Needless to say I have never heard from Telkom since and I continue to pay my contract each month for a service which is no better than what I had previously but yet costs more. I am so glad I only took a 24 month contract wish I could end it now! ***8 - case number
