Terrible service

We purchased a tumble dryer from Makro in Woodmead. A week later it stopped working so I called the branch to let them know. I received a job card number. It’s been 3 and half weeks and so far nobody has called me regarding this issue. I went to the store personally and they said they can’t help me and I need to call the office. However their line is never answered. Pathetic service and it’s almost a month later. I only used this machine once and it’s not working. Really frustrated by the service from the woodmead branch.
