LTE becomes smallband

I have always been happy with neotel's service. Unfortunately, more recently that has changed. My broadband data has dropped to 1.8mbps ( NOT an isolated reading)<br> Your call never gets answered so I used their email contact. <br> Their reply was to give me the call centre number and another email address. Why can't they forward the email.<br> Anyway, the new contact told me to get a lan cable and redo the test. 2 questions neotel:<br> Are your clients really expected to do your job for you. <br> Secondly, in a world of mobile devices I do not use lan cables. <br> There is a problem but you give me the runaround
