Samsung Microwave — unavailability of party

Address:

North West Delhi, Delhi

I have purchased a microwave oven four years ago . now the buttons of the microwave is not working. I complaint to the company 3 months ago my complaint No. is [protected].But now they are saying that we did not have the part which is to be changed ,not even a once any engineer of the company visited to my house to attend the problem of the product. It affected to my work also .
I have been mently harrased by the company so much.I am from a middle class family I cannot afford it to purchase it again & again. I suffered alot from this. I want that company should pay the penalty of this. so please do the needful.
