Can KIC provide actual customer service?

At the end of February 2018, I purchased a KIC deep freeze at house & Home, The Grove Centre, Nelspruit, Mpumalanga. In June it stopped working, I lost a lot of food then. They then contacted KIC, whom then sent a technician to repair it. Less than 3 months later it stopped working again. I reported it to House & Home on the Thursday morning and KIC said they will send a technician. They expected me to wait till Monday late morning for repairs. I refused and by the Saturday they replaced my deep freeze after long debates over the phone and also in person at the shop. I kindly requested that they refund me for my losses as it amounted to almost R4000.00. I got a quote for the items lost and send it to House & Home with photos as proof. I spoke to a representative of KIC and she just said that they don't do refunds. After several emails to House & Home, the branch manager said they will try and claim from KIC. I phoned House & Home almost a month later, because I did not get any feedback from them or KIC. Shortly after a lady from KIC phoned with a message from her boss. She said: "sorry we don't do refunds." I made it clear that that is not solving my problem and that she must ask her boss to phone me with a solution to my problem. I did not hear from them again. So now everybody is just denying responsibility for the losses I had. The first and the second times' losses amounts to far over R4000.00 For a whole month we were struggling. The meat we thought we saved in the beginning also turned out to be bad. I offered to cook them a meal with that meat and see how they like that. - Got no response. It is not acceptable that nobody takes responsibility for the products they sell to the public. This was a new deep freeze - that stopped working twice in less than 6 months after purchase. I believe that they should have replaces the product after the first time it gave trouble, but they tried to solve the problem with a repair. That was their choice not mine. But I tried to be decent about the matter. I carried the losses I had the first time, this time it is their turn. Is their anybody at KIC that is prepared to take responsibility and give actual customer service? I will not stop until I received my refund.
