Terrible service from sales representatives

I purchased a 2015 Fiat 500 on 31 August 2017 from Arnold Chatz Constantia. I was promised that a spare key would be ordered in October. I have contacted the sales consultant who replaced the initial salesman who soldy car to me three times, each time with a promise that he will respond, but he doesn't. I left numerous messages for the DP, Barret, to contact me and e-mailed him, but to no avail. It has been almost a year and I am still without a spare key for my vehicle.
