No service after 5.5 weeks of reporting problem

Make use of Afrihost's Broadband LTE service after Telkom's infrastructure collapsed in my area. I live in a full LTE coverage area (with 5 bars LTE signal on B593 router, which I bought upfront from Afrihost for R2,000). The performance of my internet connection is very slow ranging between 4MBPS to 12MBPS. Speeds advertised by Afrihost is 40MBPS+, my area also has 40MBPS capability. I started a network coverage query with Afrihost 5.5 weeks (28 October) ago, and they have not been able to resolve nor give me feedback on the progress of my problem. I've sent them speed tests and forms which I had to fill in around my issue which they got within hours of me receiving the forms (28/10/15). When following up the response is the case has been escalated and they are sorry. I pay +-R1,200 per month for this pathetic service, and cannot even get Afrihost to help in me attaining what they advertised or get a decent answer or feedback from them. I have followed up more than 20+ times with them, with no results at all. Please resolve my issue as soon as possible and fix my connection. Blame also seems to shift to MTN, but my contract is with Afrihost.
