Repair-it, day light *******

Day light *******, this guys sold me a fridge, when it go my apartment it worked for 2 days then got broken and my food was wasted, I asked them to repair it, they took a week before they could come through and collect it, then I asked them for a refund since their fridge is not working, they told me they don't refund when the appliance is working, they brought it back and it has never worked since, I reported the matter to themand asked that they should call me to check it if it's working before they could deliver, it's been almost a month now, they just ignore my calls.
