Good quality, just a A little sow to ship

This is a 200lb bag with “120kg” sharpied onto the manufactured tag of 200. It barely fit 200lbs into it let alone another 60lbs which is what 120kg converts to. The store customer service first tried to convince me that 120kg converted to 200, then I wasn’t using the correct sand.then weigh it, then send pictures. I’ve purchased six other sandbags from 3 separate suppliers, and while sometimes there are minor size differences to be expected, nothing this flagrant.
