Defy after service suck

The worst after service ever! I have invested in a new oven and paid a lot of money to buy a Defy gas/ electric oven October 2020 from a dealer in vereenigin named Diamed Corner. I have chosen a decent oven as I am in a catering business. The second time using my oven the entire stove exploded with glass every where, I emideatley contacted the dealer whereby I was notified that Defy will have to contact me and sort this out. I notified the dealer that I do have a function the comming Wednesday (the oven exploded on the Saturday) i was informed that my query will get attention in 48 hours i was so disappointed as no one wanted to help me or understood that I have a function I need to cater for. Defy only send out a technician to tell me the glass is broken. A week later still no feedback from NO ONE!!!! I phoned the technician and he gave the phone to his manager Sakkie who confirmed that my stove will be replaced I must just send my receipt and model number to his technicians phone and he will do the rest. Well tomorrow is 2 WEEKS AND DEFY IS A NO SHOW!!!!! I AM LOSING INCOME AND EVERY ONE IS JUST NOT RALING OWNERSHIP OF ONY THING. DEFY YOUR MANAGERS, DISTRIBUTORS AND SERVICE SUCK TO SAY IT LIGHTLY! if anyone is thinking of buying Defy think again because the after service is very bad!
