Stove under warranty exchange failure

I bought a freestanding Samsung 90cm gas stove/electric oven on Takealot less than a year ago. It looked great and worked perfectly. It was a great purchase...until the oven suddenly stopped heating. Called Samsung, as it was still under warranty. Call centre gave me decent service, and a technician was eventually sent out to confirm that the thermostat needed replacing; factory fault when fitted so it burnt itself out. A couple days later the technician calls to let me know there are no thermostats for that unit in the country (it's literally the only stove Samsung has on the SA market at the moment). They have decided to replace my stove entirely. "Great news, problem solved," I thought. Next thing I get an sms from Takealot saying they're coming to pick up my stove for a return under Samsung's orders. I call the Samsung and they say it was logged for replacement, so they'll take the old one and bring me a new one. I ask "what about my installation costs with the electrician and the CoC for the insurance?" Operator says she has to talk to manager, she'll phone me back. Never got an answer. In the mean time Takealot picked up the stove without bringing a new one with them. Asked them about it, but the delivery guys don't know the details, they're just told to pick it up. Two days later Takealot refunds the money for the stove. Neither Samsung nor Takealot have answers when I call them now, as a refund has been given, so the case is closed. Now I suddenly don't have a stove anymore, and I need to start shopping for one again. The stove I had is now more expensive than when I bought it as well. I'm really disappointed, as I was happy with that stove, but when the smallest thing went wrong, the company couldn't fix it. Now I'm worried about all of my other appliances which are also still under warranty, as it's all Samsung. I'm also disappointed in Takealot, as they just never gave me any straight answers, which is also a shame because I use them for all of my online shopping. I don't know which of these two companies are to blame, so I'm leaving this review for both of them. I've been a loyal customer to both of you for years now. This is not cool.
