Game misleading customers in order to make more money out of sale

Bought item online Sinotec 70" TV ,they had issues with their payment site and now they refusing to give me the item as it was was advertised on their site and for the price advertised

False and misleading advertising just to milk customers, I want someone from game to call me as if I was instore I would have still been able to take a rain check for the item with the price, so I would like to purchase the tv but for the price of R9099 as it was advertised before increasing with nearly R2000
