Woolworths taking in money on expensive underwear you can’t fit on or return

About two weeks ago I visited Woolworths and bought a body shaper. From a previous (horrible) encounter where I was buying underwear for my nephew I learned that Woolworths no longer allows fitting on of underwear. So I go to their fitting room and ask for their tape measure go in and measure myself to see which size I should take. ( they have size guidelines on the garments) luckily my mom is a seamstress so I know how to measure a body. From the measurements taken I take a size, now bear in mind it’s shapewear so it’s normal that it looks smaller so I just thought maybe that’s what it is otherwise why would they use this size guide. When I fit the item at home it could hardly go up my body. I emailed customer service and told them that their misguided size guides made me purchase the wrong size. They responded with a very vague statement where I was unsure if I should return the item (unworn and still tagged) and now they are just silent so I will start making noise! Woolworths appears to be making money off their lingerie as it’s priced high, it’s very expensive and you can’t fit in store. And once you leave the store you can’t return it. Not even when you have followed their guidelines and used their tape measure! Pathetic!
