Lalela inverter is ****

I bought the lalela inverter and after 2 months, it could not last for an hour. I tried to email them but no response. I took it back to builders where I bought it and it's also a story as they can not refund but they can only get lalela to fix it. Am not hopefully at all as the stories you get told about this product are always different. Am so frustrated right now as am not ready to drive to work after spending so much money.
