Faro store taking clients for granted

I bought shoes @ Faro Atterbury on the 25th September 2025 only to find that it's uncomfortable, I then took it back on Monday 29 September 2025 with the receipt which has the price and product code, to my surprise they are refusing to refund me because I do not have the price tag, because I threw it away not knowing that they want it as well, they are claiming that they explained to me that should I want to return it I should bring back that stupid price tag, I left both the shoes and the receipt in the store because I want my refund nothing else
