I cant cook for my daughter, cracked stove and no replacement

I bought a whirlpool stove, with my family having to have used the brand for years and i have trusted it with its quality. Bought a oven and ceramic top stove. Its still under guarantee. I logged a call with Whirlpool on the 11 Sept 2017and i still have not been replaced of my stove.

I technician came on the 21 Sept, within a minute of coming in the house he told me Whirlopool will not replace the stove and left. He did not even leave a job card nor something that confirms what he is saying.

I feel ****** and unfairly treated by a brand i loved and trusted for years.

This is frustrating me and i cant cook healthy meals for my 9 years old daughter.
