Pick n Pay online shopping is the worst !

I’m highly disappointed at Pick n Pay service . I ordered a 2 plate mini oven( Salton)stove on 19 March 2023 at Pick n Pay online shopping, they delivered a faulty stove on 20 March evening . One plate isn’t working and when you switch on that plate it’s the other that gets hot instead , it’s a mess !!!I made a call the next morning to inform them about this problem . The agent assured me that the issue will be escalated and said they will come pick up that stove and deliver a working stove but till today nothing has been done ,l have sent emails , Nokhanyo Victoria Benjane responded and took my details on 25 March but since then she has been ignoring my follow up emails , l have also sent Facebook messages but nothing has been done . I’m stuck with a faulty stove and don’t know what to do anymore. I regret buying online and using Pick n Pay , I didn’t expect such treatment and incompetence, who would have though that such a big brand would deliver a faulty stove and then ignore the customer after that !
