Kenwood and Game Poor After Sales Service

I bought a Kenwood air fryer from Game as a Christmas gift. When the box was opened the recipe book was not in the box as noted. I immediately contacted Game who weren't interested in helping. They simply referred me to Kenwood stating this needs to be addressed with Kenwood? How is this correct? The item was bought from Game? Surely Game should take this up with the manufacturer? Game supp**** contact numbers which don't work during a period when Kenwood was closed? Kenwood website was visited and there is nowhere to send an email or ask a question. I eventually used the only contacts options available (which are for servicing and orders) to ask where I an direct my enquiry or who can assist me. To date Kenwood hasn't bothered to respond. Game have also not rep**** to my request for them to assist? Such a small and simple thing causes frustrated clients to shop elsewhere and for other more accountable brands.
