Vodabucks sells faulty goods with no means to return items

I purchased a combo toaster/kettle deal on the vodabucks store in late March 2022. The kettle stopped working within a week of using it. Ive logged a return in April 2022 and made at least 7 follow-ups as to when the items will be fetched and do date - I still have the item and no refund. the only response i get is i'll reescalate... and the supervisor/manager is never available. I have even sent a few emails to ***. ***. ***
