Review used item delivered even when new purchased

MAK********
I ordered 2 inverters on line.
2 inverters arrived but one had the wires connected and there is another cable missing, you can see where it has been connected to a battery. It is a used item or Demo.
I contacted the on line number and I was given a reference, I was called on Saturday to say a new item would be delivered on Monday or Tuesday, nothing arrived. I called the number that I received the call from and the person who had called me answered and he said he cant help and gave me another number.
I have been chasing this every day and I am frustrated to death. I spoke to Cliff and he has promised all sorts of things but every time I speak to anyone the story changes. I tried to call Strubens Valley and I was treated so poorly by the receptionist, as usual the branch manager was not there, the service is appalling.
I want my inverter and I will never buy anything on line from Makro ever again, this service is appalling.
