Poor workmanship and customer care

Purchased a double door fridge which is not even a year old and after numerous attempts of using the contact page with no response then calling the contact centre only for them to send someone who was useless, we reported the fridge fault (***). They sent out a technician who arrived later than the stipulated time and I had to attend to him while in a meeting. Either they hire *********** employees or require more training as he could not account for the fault, and then said to contact the call center should the problem persist. After contacting the call centre for the 2nd time (***) the same guy said I need to make an appointment with him and work according to his hours which is not acceptable taking loadshedding into account, how can one assess the fridge when there's no power. He also said he will call me to confirm a time of which has never happened to date. Such poor customer service and such poor workmanship went into the product for it to be malfunctioning and it's not even a year old. Will never purchase any defy appliance in future. There slogan should be 'defying' customer service.
