I just want my money back, please!

I have always believed YuppieChef was a good brand, but this first purchase will be my last. I bought a kettle for my 80-year-old mother and on first use it made a loud bang and tripped the power. I returned it in December 2025 and it is now January 2026, yet I am still waiting for my refund. I only want my money back, please. Order number YCR186521.
