Tommy Hilfiger GATEWAY STORE

I purchased 3 items on their opening weekend, 24 November 2018, I then went overseas for 3 weeks, on my return I wore the shirt for the first time, my husband saw a flaw in the fabric on the front, I immediately took it off and called the store as I don't live close, the sales person said it was just over the 30 day returns policy, (which I presume is if you change your mind and not if it has a defect!!) I said I would come in and bring my plane ticket as proof of being away. When I went into the store the sales lady treated me like a ********, asking why I took the tag off, which I had together with my slip, she called her manager and the owner and they refused to replace it saying I should have checked it before I bought it!! disgusting service!! I am definitely going to take this further
