Incomplete Solar Installation

I started a solar installation with ELECHTECH in February 2024 . It is now almost end of July 2924 and I'm still waiting for Sakkie Linde the owner to finish my solar installation. It is only partially complete. The owner, Sakkie keeps lying about stock and makes promises to call and complete the job but nothing has happened. I have made numerous calls and sent numerous messages but nothing is happening. The owner Sakkie has too many excuses and false promises. He also his business profile to temporary close afte i gave him a 2 star review a few months prior.the business after I gave him a poor review Sakkie ignores calls, and messages.
