Wrong pricing at Steers Birch Acres Mall and bad attitude

I got to the store and they displayed meals in specific prices, upon ordering the prices have changed on the tills and are more expensive. I then asked the manager that why are they false advertising and he said there is nothing he can do. The Manager named Emmanuel and kiosk teller named Magdeline had attitude and insisted they can not do anything or sell the meals at the prices they have displayed in store.
