The absolute worst service experience

After an internet outage our ISP confirmed that the issue is with Vuma and created a ticket. A Vuma technician phoned us and advised that they’ll send someone. Nothing happened. After following up we were informed that the ticket had been closed claiming that there is no fault from their side. We created a new ticket, and it was the same story except this time Vuma insisted that the fault is with our router. The person on the phone clearly had no technical knowledge and we explained more than once that we tested with another router and connected directly to the ONT with an ethernet cable. The ticket was closed again. We finally gave up and engaged the services of another fibre provider and guess what? The internet works perfectly and the issue was not the router. We are out hundreds of Rands worth of mobile data since we work from home because Vuma can't be bothered to fix a service we pay for.
