Broken product

I actually not wanting to write a review. Just wanted help. I like the item but wore white band twice and band loop broke. The turquoise one never worn and has no buckle. Please help or replace. The summer colors is why I bought the product. Today I go to use the Navy band. And it is actually a size small, Not large like the rest of them This is now 3 that are not right and can’t use
