Reported a grill oven element faulty to the Bellville branch

Reported a grill oven element faulty to the Bellville branch. They acknowledged but after seven days, no response. After contacting them again, took another 2 days to repair. Same day after repair, oven light started fusing. Replaced light twice then reported it as I felt it was related to previous fault. Again after reporting it, took 12 days to repair. Left with oven in a filthy state after working on it. All contact emails for Defy has been returned undelivered. Poor customer service
