Woolies disappoints

I live in George . Woolies stores are very disappointing . I wanted to buy men’s shorts in each colour specifically PULL ON TWILL CARGO SHORTS. None in a medium size in the store 😕 The kind Woolies assistant checked stocks for online and confirmed stock available . I tried to order online - result is Out If Stock. Really , this can’t be the case in Woolies nationwide 😩 HELP
