Complaint about my washing machine that is still under guarantee

On the 26th of September I went to Makro Woodmead where I had bought my washing machine (it is on extended guarantee or warrantee until 2018). I told them that my washing machine does not wash the clothes properly and it leaves washing powder on the clothes. They took my details and I was told that I would be contacted within 48 hrs and that did not happen. I called Makro after waiting for almost a week. They took my details again and nothing was done. I eventually called again and asked for the store or Appliance manager and it also took time. After making countless call, they sent a technician from Panaservices on Thursday 05 October and the technician indicated that my call was only logged on the 04th of October after 16:00. The technician was not able to fix my machine and told me that he will he will arrange for the machine to be picked up on the next day as his bakkie was already full. The machine was only picked up on the 9th of October and returned on the 13th. On Saturday when I tested the machine it still had the same problem that it initially had. So I called Tshepiso (Appliance Manager from Makro) and explained this, he said he will write an email but will only get a response on Monday. Monday morning I was called by Panaservices and they sent a technician who asked me once again what is the problem with the machine and when I told him he told they need to take back the machine as they thought the machine was not working and they had not tested what I told them. So my machine was taken away again yesterday. I have spent a lot of my time and money and since the 26th of September till now. My patience has ran out and understandably so. Makro must sought this out. They rather take their machine and give me my money I have been more than patient.
