Is "Old Man Emu" in frail care?

Since 11 February I have been trying to purchase an "Old Man Emu" suspension kit for my 2012 Toyota Fortuner. Three quarters of the kit has been available but the rear coil springs have not been in stock.

Firstly, I struggle to understand how one component of a kit would be out of stock as the 4 components are all part of a complete unit that are installed and work together.

Secondly, I am rather disappointed that "4X4 Megaworld" who have been awarded the sole exclusive National franchise for this product can allow such an integral component to be "out of stock".

Thirdly, 4X4 Megaworld cannot give the agents any idea of a delivery date, despite the fact that the container with the goods has allegedly arrived in Cape Town. In fact, if I understand correctly, the local agent that I am dealing with has repeatedly been given "hollow" assurances that the rear coils springs will be available within a few days and upon enquiry are told the same thing again and again.

It has been more than two months since my original attempt to secure this product. I will be leaving on an off road adventure in the middle of next month that is tailor made for OME suspension, but despite having already paid 50% deposit, I have no assurance from 4X4 Megaworld that I will have the product installed.

I wonder if Old Man Emu holding company in Australia is aware of our frustrations and the inability of their franchisee to deliver their product.
