Missing alloy wheel not replaced after 7! month

I bought a Toyota Verso in May 2015, when I picked up the license after having driven it on a temp license for some days I noticed that it only had 3 alloy rims and 1 steel rim, I wonder how they did get it through the roadworthy test like that. Michael was supposed to get the 4th alloy rim and fix that problem but still hasn't. I've sent several emails reminding him, he asked about the size of the rim on 16.09.2015 but to date it still has not been sorted out!
