Treating unworn bras like underpants costs my pensioner mother R300. Where is the logic?

I am writing this to challenge a completely flawed, illogical policy enforcement by Pick n Pay Clothing that has directly taken advantage of a vulnerable consumer. My mother, who is a government pensioner, recently bought three bras from Pick n Pay, totaling R300. As a pensioner on a very tight fixed budget, R300 is a significant amount of money to lose. Because it was logistically impossible for her to travel back to the store in person, she called your Customer Care hotline the very next day (Monday) simply to ask for a size exchange. She was flatly rejected based on a generic script stating "no underwear returns". I followed up via email to reason with your team, but no matter how much logic I app****, I was met with the same automated, robotic wall. Let’s look at the actual logic here. How can Pick n Pay classify a structural upper-body garment like a bra under the exact same hygiene blanket as underpants? By this exact same logic, a standard t-shirt or a crop top should also be completely nonreturnable because it touches the exact same areas of skin. Treating a pristine, upper-body item with all its original tags and labels fully intact as a hygiene risk makes absolutely no sense. Pick n Pay used to proudly operate under the slogan that "the customer is always queen." Since when did that stop being the case? We are not asking for a cash refund on used goods. We are asking for a simple size exchange on pristine, tagged items so a pensioner doesn't lose R300 on garments she cannot wear. I am bypassing your automated hotline and email bots to ask a real human in your corporate division: Can someone please apply common sense to this situation and authorize a size exchange for my mother
