Sunsynk Inverter repairs much to slow

My Problem is with Service by Sunsynk of the Inverter. I had the System installed just over 2 years and very good but now after getting Thula Moya was contacted on the weekend of 14 July 2024 contacted them to let them know there is a problem, and it is not working. Devin immediately rep**** and as promised sent someone on the Monday to see what was wrong. They removed it as they said it would have to go to Sunsynk to be repaired. that was going in during that week. I have followed up on a few occasions and was told that Sunsynk is very slow with their repairs. It is now the 23rd August and still no feedback on when I can get it back and installed. Totally unacceptable with still no Invertor having been repaired and re-installed.
