correct size, wrong cut, wrong size, correct cut, bad return policy

The previous Levi's I bought were all of one size and one cut, and they all fit nicely. Then came the pair I purchased before this one, and while the label was the same as before, the new pair didn't fit. Did I gain weight? I tried one more pair and they are now obviously too big.When I attempted to return the missed labelled pair, Amazon at first refused to refund my money. Only after I called them on the phone they gave me a refund. I thought they have a "satisfaction guaranteed" policy. I didn't return the last pair even though they are too big, I don't need the frustration of dealing with their complaints department again over missed labelled product.The next pair I buy will be from a local store, where I can try them on first.
