Correspondence very bad

We bought a Candy washing mashing in August from Makro, who's service is also bad. Mastercare sent me an sms with a job number. I phoned them to know when a technician is going to come and inspect the appliance. They informed me it will be within 3 to 4 working days. After the fourth working day, I phoned them again to find out when he is coming, where they notified me that it will be later in that day just after 17:00 nobody showed. Only at 20:30 after our kids was in bed the Technician rocked up. All he did was to take pictures of the serial number and of the damage. If that was all that was needed to be done I could have sent the pictures myself. He Was there on 28/10/2021. They sent a message that the part has been ordered on 29/10/2021. Four WORKING DAYS have passed again with no ETA on when my appliance is going to be repaired. Then when you phone the customer care line the welcome message claims that Mastercare is the No1 Leading Appliance repair company in South Africa. So ask yourself the question: Do I have reason to be frustrated?
