Whirlpool India — Convection oven

Address:

Chennithala house, Perunna po, Changanacherry

We bought an oven. Magicook 32 litres. Today it's warranty get expairs. So many complaints during this warranty period itself. Service men came and replaced the transformer. Now it is showing the same complaint. It stars without setting the temperature and the food inside the cavity gets cooked by just turning the mains on. I don't know what to do. This product is not good. We want to return it. We spend 15000 on it and how is it possible that we can't use it in good condition for at least an year?
