No Service

I bought a Hisense fridge in Aprill 2014, and still paid an extra R615 for extended warranty. On Friday, 23.10.2015, came home from work to find my fridge defrosted & not working. Called the store on Saturday morning and was told to come into the store with the receipt and extended warranty slip & a technician will be sent to my house that afternoon. Get to the store and was informed that there are no technicians working on weekends. i had to leave the store with not even a loan fridge, so had no fridge the entire weekend and spoiled food from a fridge not working. i had to even give away meat & stuff from my fridge/freezer as everything was defrosted from Friday. got to work Monday morning, 26.10.2015, and called Hisense directly, only to hear that Hi-Fi Corp did not even log the complaint with them. At the moment i am not even sure for how much longer i have to be without a fridge. who will re-imburse me for another months groceries as i had done my monthly groceries just before my fridge stopped working? i was told in the store that a max of R500 gets re-imbursed for spoiled food...who buys R500 worth of groceries nowadays???is it the right of the public to know of such service.
