Game Stores False Advertising!!!!

I saw an advert in the game paper advertising two Princess BMX's both for R499 (Saving) R129 + a free helmet valued at R99. I sent my sister in law to purchase these two bikes at the GREAT price of R499 for both. She went early on the 13th December 2018, but she was advised that this is a miss print. Now I am terribly sorry but to my knowledge the price you see is the price you pay. The promotion runs until the 18th December 2018. I have also gone on to za catalog-24.com today the 14th December 2018 to make sure of the price advertised and sure enough it is still at R499 no where is there a retraction notice or an apology for the miss print. Consumer protection act please have a look into this as this is very miss leading to the public to get the foot traffic into the store. I feel that Game Store should honor this price as we especially went into this store for this deal!!! Disgusting Game!!
