Bad Service

3-years ago Grid Freedom Group (GFG) were asked to replace a ****** SMA inverter and solar panels. Once the task was completed they were paid. However, shortly thereafter the system started failing. GFG dispatched their representative, Mr Ross Muller, to attend to the problem. He came 6 times and sometimes would get the system to work for a maximum of 1 month. On other occasions he would need to refer to the manufacturers, SMA, for assistance. Currently the 35kW system is producing 5kW. Over the 3-year period that this has gone on it has resulted in a large loss of revenue to my company. Of late Mr Muller is not even returning my calls as I mentioned a month ago that it may be necessary to revert to social media to resolve this problem.
