False adverting price savings on specials

Misleading public on promotions savings and false advertising. Be very very careful I was caught addressed it with Game head office , logged a call and still no feedback. Be very very careful game advertises a saving and a specials promo price but they don’t keep to the so called savings one makes buying the promotional item. Pity this forum does not let one add photos as I would be more than happy to share the slip info, the system pic of normal price and also the price of signage giving so called amount saving and special price. If anyone can advise on where and how to log this with the retails board etc and other platforms for false adverting and misleading public
