2 NWOT Daisy Bras inaccurate sizing

You have probably seen them advertised on FB and IG. The grandma that created a better bra, called the Daisy bra. I fell for it. My order was for size 38DDD. What I received looks like maybe a 36 B or C cup. Bra snaps in front. Pictures show some of the claims from the advertising. Usually sold for anywhere from $15 - $50. And BTW, yes, I did try to return them. Several attempts with No response from company.
