Bad service experience

The week before last I had an issue with my gosolr inverter, upon installation I was informed that the system is monitored remotely. A warning message was dispatched three days before I had loadshedding, no one detected the warning message, and I was inconvenienced as my batteries were flat. A technician visited my house after a week, surprisingly on the 19/03/2025 our area had interruptions from Eskom side, however I was once again in darkness with the same issue which was supposed to have been rectified.

I wrote a complain letter and still awaiting a response. My old ticket has been reopened apparently however, call center agents cannot even give an estimated TAT for a technician to come out.
