LTE Not Working in Advertised Coverage Area

I am very unimpressed, I bought an LTE package on contract from Telkom as my area is 'covered', I live in Haig Rd, University Estate Cape Town. HOWEVER the signal is really dreadful, having used LTE in Claremont and Kenilworth before. The speed is very slow and the signal is intermittent, not always available and often dropping to 3G and even 2G. I have had to buy an external LTE aerial as when it is windy or raining there is sometimes no signal at all.<br> <br> I am now paying for something that is not functioning as advertised. Having tested my LTE in Claremont and Kenilworth previously I would get about 15 to 20 Mbps download speed whereas now I am lucky if I get 5 Mbps (with an external aerial). This is when the LTE is able to connect and not revert to 3G. I am experienced with computers and the internet and DO NOT think University Estate should be advertised on your coverage map as having LTE as where I live this is not the case. Please address this issue as I am sure other people living higher up in University Estate and other areas must be having a similar problem.<br> <br> Mr NS Cronwright<br> [Email Removed]
