screws that don't work

bought these stainless screws to screw "down" 2x6 pt decking. they would lift the 2x6 and then not draw it tight to pt joist. I contacted your chat now and was told to back screw off, push down on board and tighten screw and board down. this sort of worked if I screwed it aprox 1/2" into 2x6, didn't like that fix. Prior to purchase I asked chat now if I should use 3 1/2" for the 2x6, was told 3" would be fine. To sum it up I wound up buying 3 1/2" deck screws (not ss) from lumber yard, these worked like a screw is supposed to and tightened the 2x6 to joist without any gymnastics. I still have the 10 lbs of useless screws.
