misleading

Hi to whom it may concern I'm very dissapointed in games adverti*****ts they advertised sinotec tablets 7inch 2 tablets buy one get one free . When I came by the store the morning at 10:30 on the 7 Aug they told me the tablets is sold out at all stores .misleading customers to come to the store and let them buy something else I made copies of the papers they pasted up in stores says sinotec is sold out for today 7August did not say limited stock available for each store
