Rank Arena Air Fryer

I have written before about my Rank Arena Air Fryer, I went on to ring Rank Arena, I left messages but to date I haven't received a reply. Very disappointed with the Rank Arena Air Fryer and after sales service I would never buy any of their products...

I purchased air fryer from deals direct. It worked once and only cooked three lots then stopped. Went to use today will heat up but does not have air sound. Not happy. What can I do about it. You expect things to work at that price. Can you advise me...
