Rude manager

I bought a fridge from Makro on the 3rd Nov 2018. The freezer is operational but the fridge is not cooling correctly. I contacted Defy on monday to request a technician to come through. finally after following up Sibu informed me that a the call is logged today and the technician would phone me to arrange a time. I phoned this morning because NO one has phoned me and I need to know who will be coming into my personal space and what time. I phone Defy this morning at 9:30am to find out what time and was told they cant give me a time. I asked if I can get the technicians number and I am told that I am not allowed to phone them myself. I requested to speak to the manager and Thando was rude and spoke to me like I was her child. She also refused to assist me and I know the calls are recorded. It is now 1pm and still Tshabalala has not phoned. I have to arrange for someone to be there and yet your staff dont give a dam about my time. I want my fridge fixed or replaced now. I have food going off because of your faulty product.
