Mellerware bad service

i bought a kettle from Mellerware in 2016. I registered online to get a 2 year warranty. I got the confirmation email to say I have successfully registered my product. First the button broke for the lid to left, then it started leaking, in April before the 2 year warranty it wouldn't go on at all. when I emailed Garth at Mellerware he was totally unhelpful and told me that there was no slip uploaded with my registration. I find this hard to believe because if it asked me to upload my slip I would of. on the registration it had the date of purchase, product number and a receipt number. They could see that I was not chancing. He gave me no other assistance and did not answer my question when I asked him how much more proof of purchase did he need? the kettle is ******* and other people I know with the same kettle has had the same issues with leaking and the button. Definitely not the service I expected from Mellerware
