Very angry customer

am very unhappy with the service i am getting from Telkom Direct Century City. I gave them my phone so that it can be repaired on 28.11.2020 they gave me reference number TRJ129700. Everytime when i call them they give me a run around. Until today i don't know when will i get my phone. Its holidays all alone at home with no phone. How must i communicate with people?? Its been more than 21 business days still no communication or a phone. Please do contact me urgently on ***. As soon as i get my phone i am canceling my contract. This is absolute nonsense!!
