Disgusting customer service: Galaxy watch Active 2

I purchased a Galaxy watch Active 2 online. You are not able to select a strap size when ordering. My watch has come with a strap size Medium/Large, which is so big I cannot even wear my watch as it slides off. Samsung refuses to exchange the strap for a smaller one because it is seen as an accessory. This is absolutely disgusting- all other watch brands have straps in various sizes. Now I need to pay more than any other customer to purchase a strap separately, that may or may not fit my wrist. I don't even think Samsung manufactures a smaller sized strap as I am unable to find a replacement that will fit my wrist. Samsung is discriminating against people with smaller sized wrists and I am told they cannot do anything to assist me.
