Disgusted in defy

I am beyond angry - I purchased a defy slimline stove top in May 2021 last year they had to come replace the control board which was clearly faulty - on the 30th of May this year the board burnt out again and now a few days out of the warranty period Defy wants me to pay 650 for a call out fee , 170 for every half hour they spend trying to fix your appliance and spare parts will be charged separately - This is daylight ******* clearly their appliances are faulty and why would they give you a 3 year warranty on the oven and a 2 year of the stove top when you purchased it as 1 appliance this boggles my mind - this will be my last defy purchase ever this just makes me sick to my stomach clearly only care about money and not about their customers - also how can the warranty be from date of purchase when I purchased the product online and never had the appliance in my possession yet Im so disgusted. - *******
