Faber — gas stove 3 burner

I have bought faber gas stove from vijay sales gurugram. After purchasing one week faber gas stove auto ignition problem occured and engineer come repair the gas stove. After one month again same problem occured now 2 burner out of 3 not working. I am very unhappy with this product. This is my humbble request to you please replace my gas stove it is total worst product. I will never recommand faber product. And also it is safety matter. I think my problem will resolve shortly
