Useless support on technical problems !!!

After my loadshedding ended on friday 23 June 2023 my conlog wUIUX pre-paid meter popped up a spanner or wrench symbol (user guide states that it is a "technical problem: contact the supply authority" , I've been without electricity since and nobody has come back to me to resolve the problem. I have made multiple calls to +27 (31) *** but no one answers and the call ends. If support does not work over weekend how do I have to live in darkness for a full weekend with your device's technical problem.

Your prompt response is the least I expect as a paying customer !!!
