Customer care not bothering to respond

I purchased a Canon 70D from takealot three weeks ago when it was on special, about a week ago the LCD screen went dead on the camera, so I called their returns department, they in turn logged a support case as they do not have stock to swop it out and I am not willing for them to repair a new camera. I have since then tried calling and sending emails, each time being promised they will get back to me. I am still waiting for someone to make the effort to make contact with me. This is not acceptable!
