Deceiving prices on burger meals

I ordered a whopper with cheese meal on uber eats only to realize once the order was delivered that the burgers was junior whopper burgers. We sent it back only for the Burger king to say that the order was correct. I checked on the app and realized the price for a normal whopper is meal R77, the the junior whopper meal is R76. That's a difference only R1!!! Ofcourse I would have paid the extra R1 if I knew that. Absolutely disgusted with this, never buying from burger king ever again.
