Poor Service from CMH!

Hi,

I brought my cx-3 to Mazda Randburg initially on 13/2 for a knocking sound. I was advised by Ronald that I should book car in. I booked it in for 22/2 to have the struts/shocks tightened. This did not fix it. I then rebooked car for 11/3. I was told that the shock will be replaced and 1 would be ordered. I was told by Liesel that she will call me when the part arrives. Since then I called Ronald twice who meant to check if part arrived and call me back. He did not. I called a week ago and left 2 messages: 1 with Ronald and 1 with reception for Liesel to call me but still no response. Its more than 2 months and I'm no closer to a resolution.
