Terrible service - robbing customers

Bought a mellerware induction cooker in September 2020. November 2020 one of the plates stopped working , bear in mind this item has a two year guarantee. I returned the stove and it has been three weeks and no feed back , called a few times and getting hold of customer care at the Cornubia branch is like getting hold of a celebrity ,you just cannot get through. Eventually after getting through guess what - they cannot pick up any returns on my card number. Pathetic - *******s , honestly i would rather stick to game , hirsch and checkers for appliances they are fair more competent and reliable and they do not rob their customers.
