WASTE OF TIME

Good day I have been having so many problems with these competitions that when I dial the numbers given to us on the bottle (*120*2653#)it takes so long and takes a lot of air time just to tell me they are very busy please try again late and so I do with the same number and guess what, it now say the number you have tried has been used or incorrect please try again and each time it just keeps taking up all my air time. THIS COMPETITION WITH COKE IS JUST A WAIT OF AIR TIME.
