Poor Aftersales Service/Faulty Machine

Reported a faulty Bosch Machine which I bought from game and the sales person by the name of Karabo(Game Soshanguve) did everything to log the query and was sent an sms on the same day(14/05/2019) with the reference number(BJ130283) which confirmed that a Technician will contact me within 24hrs. On wednesday I Contact the call centre number on ********** at around 15h00 as the Technician did not contact me and was told that he will come on Thursday which never happened again. Yesterday I contacted them again and they told me that the Technician will come as he was around Pretoria. He called me around 17h00 telling me that He was coming but stuck in Traffic and I waited till 20h00 and I called him again to find out his whereabouts and he told me that he will see me tomorrow and he was in a noisy place, it sounded that he was at a Shebeen or Tavern. I want game to come and take their Machine and Refund me as I have Bought another machine, this is poor service from Bosch and unprofessional behaviour. I WILL ADVISE PEOPLE NOT TO BUY ANYTHING FROM BOSCH, STAFF IS ***********, UNPROFESSIONAL AND PATHETIC *****.
