LTE Advanced Internet link speed less than 1 meg

I have subscribed to LTE Advanced Internet package, I was informed that the speed would be greater than my previously installed ADSL line. Since August 2015 when it was installed I have reported this unstable internet supply. After many weeks since installation, 2 technicians came to move the outer aerial but still no better. My last call (of about 20 I have made) was made on the 07/02/2016 case nr ***6 where I informed them that they must cancel my contract and reinstall my ADSL line and provide an internet provider as the current setup does not work properly. Or make Fibre available in my area as an option. I work from home and earn money as a IT consultant and just cannot work like this anymore. I hope that this complaint will get some reaction as I cannot seem to get any reaction by phoning the call centre. Besides reporting my breached contract to the consumer protection council as I did not get what I pay for I don't know what to do. I pay R707.50 per month for a service that is not as promised. Please can my complaint be addressed and have it attended to by experienced and qualified technicians .
