inverters - but the alternative!!!

absolutely the worst service I have experienced in many years. Had a new inverter, literally shower sparks without any connections - other than the batteries. I turned on the unit to check if any residual charge on the batteries before any input or output connections made. Sparks and small flames ensued. but THAT is not the major complaint. from many years in the electronic industry, I knew that this malfunction would be difficult to prove. So took to Woodmead for them to investigate. 2 & half months later no response.. Phone them often but rarely can get thru' - seems always 'busy' & whenever successful I am told the manager will phone me back - obviously does not!! paid R10.999 for a unit that never worked and cannot get ANY feedback from them. would never wish retrenchments on anybody but the fact that the company is seeking a section 189 does not come as a surprise......
