Broken Fridge

I bought a fridge from Teljoy and when i finished paying it I took a service contract on it. soon after that my fridge stopped cooling. Since january I am still sitting with a broken Fridge. They keep sending someone to fix the fridge but its still broken. So in May the Fridge worked briefly for two days. I then cancelled the service contract as I gave the fridge to someone else. As soon as i cancelled it, the fridge broke again. Same problem, they assured me they will repair it as the repair is still under warranty. To date this fridge is still broken. They are now refusing to give a new fridge because the service contract was cancelled in May. You have been messing us around. Not to mention all the food we have lost which has gone off valued at at least R3000. I want a new fridge and compensation for all the food we lost and the hassle. I have a little baby girl and all this time could not keep her milk fresh. I give you one last chance teljoy.
