Faulty kettle

I purchased a Mellaware kettle last year in November from [URL Removed] which is now [URL Removed] It was a really nice looking kettle, glass with red LED lights. The kettle then just stopped working in May. I then requested to have to kettle picked up and wanted a refund as I already spent money buying another one. I then waited for a while to have it collected. Eventually it was collected and then no one got back to me for more then 2 weeks. Finally someone got back to me saying it will be refunded once it has gone through checks. Again a long time passed (about 2 weeks) no one got back to me. I emailed and they said my banking details needs to be entered in order to process a refund. I sent my banking details. Another 2 weeks passed and then I emailed yesterday and they said they going to see how far it is. An hour later I got a delivery from them with the same kettle which I specifically said I didn't want back. Now they saying it cant be refunded coz too much time has passed. Then why the hell did they say I was going to get my money back! I will never recommend anyone buy from this *********** company and will take to social media about this as well!
