Bad service

Wish i could give a 0 star review my boyfriend and i saw the McDonald's grown up happy meal and went to McDonald's East Rand Value Mall to find out how it works and i was very disappointed in the service the lady told me i could get the socks as the "toy" with the grown up R49 happy meal i was really excited because it was really adorable we then paid and went to the second window to collect our food then they said to us no sorry you need to pay R40 for the socks you cant get it as the "toy" so i got really mad because why not say this before we pay because we only bought the deal because the lady said we can get the socks with so after the peraon who works at the window where you collect the food told as this we asked for the lady who told us we can get the socks then she had a other story where se said no so told us its R40 extra for the socks because that money goes to charity well if she told me this in the beginning i would have bought 2 pairs of socks and not the meal because it goes to a good cause and i really like giving back to charity i wouldn't have thought twice to purchase more than one pair of socks so i am really put off by there service and the way they **** to get met to spend more money rather than telling me the truth and i would have ended up spending more money
