Mcdonalds Thievery

Such a joke , got a "discount" on a flight from Mcdonalds for Safair as a prize for up sizing my meal only to find that the discount is no discount at all. The McDonalds site for the ticket is R1299 but the Safair site price is R899 for the past 2 weeks .... i would have had to pay more and McDonalds would have probably pocketed the excess cash ... blatant thievery from a major global corporation , absolutely disgusting !
