Unhappiness with Clicks Sandwich toaster

My wife purchased snack witch toaster as a Christmas present. I was very happy and unboxed to use it as per written instructions. There is no warning signs anywhere to warn users to be cautious of the hot sides and as I touched the side,I burnt my hands badly. I rushed to put my hands under running water and struggled with the pain. One the unit cooled down, I wiped it and put it back into the original packaging and waited for my wife to return home to show her what had happened. She was also not happy with the bad design meaning that children will also get burnt if they decided to use the Clicks toaster. She struggled to find the receipt but managed to get it recently and now I would like to return the item for a full refund. Please advise whom I should speak to at Benmore Clicks to arrange this refund for the sandwich toaster. Also about a year ago, I bought a make-up mirror with magnification and back light. When I put in the batteries, it worked well but my wife never used the back light feature tried to use the light during lockdown and realised that the light switches on but refuses to switch off no matter how many times I try on touchscreen. I don’t have the receipt for this mirror light and my wife uses the mirror daily so I cannot take it back to Clicks unless a replacement is immediately available. The sad part about these items is the nice to look at and use but the quality seems to be very bad for a highly reputable company such as Clicks. I am unsure how to proceed to have the sandwich toaster returned and the Round mirror with back light replaced. Can someone from customer care respond with guidance and advice? Injured customer. ***
