Unsatisfied customer

I bought an Mellerware iron at kit kat on the 1st of Jan 2025,now the iron is not working I returned it to the shop.I'm being told of the guarantee of the iron is 1 year which is what know but to my surprise I'm being told the shop warranty is 6 months,me as a customer I'm returning what I bought in the shop for them to return to the supplier or they must exchange for me not tell me stories.
