Product not as per website

I purchased a couple of items from Lovemilo and when I received the laptop clutch it was too small. According to the website the measurements are 35cm X 42cm, however mine is merely 33cm X 38cm which now means I cannot use the clutch. Lovemilo now expects me to pay the delivery fees to have the clutch refunded by them. How ridiculous is that. I would have not bought the clutch if I had known the measurements would be smaller than advertised as the laptop cannot fit. I am very disappointed and won't buy from them again.
