"No Cup Gaps Ever" - totally false claim

The size chart, to which I measured myself multiple times to make absolutely sure, told me I am a 34AA. So after saving literally (not the millenial figuratively meaning) MONTHS to get a bra after almost 20 years of ill-fitting ones, I ended up wasting $200CAD on only 2 bras because the size chart was not, in fact, true and when I emailed it was suggested I buy a 34AAA.
That size doesn't exist. It isn't on the size chart nor the options to purchase. So in reality, these bras do not fit all small breasts. Even more so, some of the models like the old woman have obviously larger chests than "small", with underboob, so how they looked online was different than when they showed up on people with actual small breasts.
Unfortunately since I live in Canada, I would lose the initial shipping costs, return shipping costs, and the $9.99 they take for returning it, PLUS I would have to buy and pay more shipping to get another, as there aren't exchanges for us up north.
Also, if you buy a "racerback" bra, the straps aren't nearly long enough to wear it that way. I ended up cutting mine and adding more material. Just total garbage.
