Bad customer service and false advertising of refunds!

I made a purchase online 01/09/2022 received parcel the 07/09/2022, not happy, dresses were small and not as per sizing chart. I sent an email the same day stating I wanted to return the parcel. No feedback received. Sent another email 13/09/2022, still no reply. Sent messages via IG and FB still no reply. I eventually messaged all the admin numbers on their wats app advertising group and eventually got a response. Just to be told that they do not do returns, exchanges or refunds. I went on to their website and screenshot where it says returns are accepted 30 days after delivery and return costs to be paid by customer. I sent this screen shot back to the lady whereby she read it but did not reply. I have currently logged a complaint with the consumer goods and services ombudsman and they are dealing with this matter.
