Samsung stove malfunctioning

I was promised to get email which I never received it till today, email was supposed to have attached consumer documents pertaining policies of the fact that if pesticide might be the cause of the stove damage then the warranty get voided. The purchase slip I have signed for doesn't contain any pesticides information.

Samsung should you have attended to my problem three months after the purchase I wouldn't be having this kind of problem because it started with one plate and I reported to House and home and to Samsung as well. Samsung professionally refuse to help me by saying it is a connection problem, now you are saying it is pesticide. How sure are you that pesticide break my stove? All the allegation are to show you don't value your client happiness you only want money period.

Please fix my stove and stop making me to regret using your appliances.

Thanking you in advance.
