Makro cape gate repair centre ***

About 6 weeks ago I returned my laptop device to the Cape Gate Makro repair centre due to issues with my device. When returning the device for repairs I was informed that it will take about two to three weeks for my device to be returned, it has now been 6 weeks. I have called the repair centre on two occasions, both occasions I have asked the consultant to check the status of my device and when I will be receiving it back, they advised that they will get someone to call the repair centre and give me a call back. On both these occasions I have received no feedback, this is pathetic. I am a part time student in my final year and have exams coming up. I need my device back urgently. I am heading into the second month now of not having my device which I was advised will take two to three weeks to be fixed.
