Unresolved issues and unacceptable service

I've been struggling for months now with unreliable and intermittent LTE service. My downloads range between 512kb & 1mb and between 200ms & 400ms latency. My connection is also not stable enough to keep me sessions active and often have to restart my downloads or sessions. I also often need to restart the router to re-establish the connection as the router shows connected, but the receive counter doesn't increment. I've reported numerous faults and have had numerous technicians onsite. All of them recon that the coverage at my premises is not sufficient for a stable connection. More than one Telkom call centre agent has suggested that I cancel my service as they don't think anything else can be done. I proceeded to apply for a cancellation which took 3 weeks to even get a response. Telkom then insisted on installing another directional antennae and sent another technician onsite for this. The technician installed the antennae and retested the connectivity only to advise that the signal quality is still not acceptable for a stable connection. I monitored the service and did a few tests and still only get around 1MB download speed and still need to restart the router to re-establish connectivity. I then proceeded to apply for another cancellation as I'm not prepared to continue paying for an LTE service that I'm not able to use. It's been two weeks now and Telkom have still not followed up on the antennae installing, nor reacted to my cancellation request. After contacting the call center I was told that they have no feedback and have to escalate the fault again. How long do clients have to endure these endless delays and continue paying for services that cannot be supp****.
