No service, no update, no worries

I am in tech and work from permanently and have been having random minor service interruptions for months now. Its generally just inconvenient and annoying but seldom a major issue. It ranged from a few minutes to a couple hours but seldom during work hours. Until now. On the 26 July my line went down for over an hour and I logged a call. ISP-823259. Line came back up again and I stepped out for lunch ~12h30.

Vumatel techician called a few minutes later to say he noticed an issue and was going to do a "configuration". I got home 30min later to find no connection.

Its now 18h00 on the 27 July and I still have not heard from Vumatel. I spoken countless times to my ISP, Afrihost but the issue falls on deaf Vumatel ears. You do not have the decency to even return a call.

I have had to get producre a LTE modem and SIM to enable myself to work and I doubt you nor Afrihost will reimburse me.

Please have you technician unconfig whatever he configured or just fix the issues! Your incompetence is messing with peoples livelihoods. Why should I hand over my money to a company that cannot provide the service?
