Telkom LTE has vanished!!

For the past week Telkom's fixed LTE at my home has been non-existent. Rebooting and resetting the modem has not helped. After clearly explaining the issue to them on 14/3, their limp reply 4 days later was to request the number in question. I have been almost a week without service. If only this could reflect on my bill. This lack of urgency is extremely annoying but not unexpected, sadly.
