Missing parts for air brush.

In December I bought a Tradeair Air Brush Set from Makro in Polokwane. When I got home I had to gut open the hard plastic envelope that it had come in. I looked at the set and as I was not going to use it right away, I packed it into a small box as the packaging was now cut open. When I eventually came to use it I discovered that the fitting which connects the set to my compressor was missing. I went back to Makro and spoke to Lesiba Manamela who told me that if I did not have the original packaging he could not help me. Not too happy with this I phoned Makro's toll line and spoke to Yolanda and told her my story. She said that she would speak to Lesiba and come back to by close of business the following day. This did of course happen, and I again phoned and spoke to Yolanda again, who promise me that she would come back to on Monday, 9th Feb 2015. This again did not happen. So Now I sit with an air brush that is useless. I cannot find the fitting I need to couple this with my compressor as they are not sold loose anywhere. What should I do now, chuck this load of **** away and spend another R179.00 to buy another Air Brush Set?????? <div><br></div><div><em>(Supplier name changed from Game to Makro by Hellopeter.com)</em></div>
