Poor service and connectivity from Axxess/Telkom

I have had nothing bad bad service from this ISP this last week. I took one of their Telkom LTE offerings but have had terrible connectivity the last week plus. On Wednesday after filling their form in they said they were reporting it to Telkom. Since then not only has nothing been done, my line speed and stability has only degraded further. Barely getting 2Mbps if I am lucky, sometimes I am even getting under 500kbps, this on a 20Mbps. Their staff are clearly not interested in trying to be proactive and resolving issues, but seem to have a don't give a damn attitude and expect me to wait seemingly indefinitely for feedback. Several recent emails have received no response beyond their autoresponder. I am done with this abysmal level of service and this company. I have actively started looking for alternatives elsewhere.
